Detailed Description

SI470X Defined Data Types.

Defined Data Types is a way to represent the SI470X registers information

Some information appears to be inaccurate due to translation problems from Chinese to English.

The information shown here was extracted from Datasheet:

SI470X stereo FM digital tuning radio documentation.

Other information seems incomplete even in the original Chinese Datasheet.

For example: Reg 10 (0x0A). There is no information about it. The Reg11 and 12 seem wrong

union si470x_reg03

Channe.

Channel value for tune operation. If BAND 05h[7:6] = 00, then Freq (MHz) = Spacing (MHz) x Channel + 87.5 MHz.

If BAND 05h[7:6] = 01, BAND 05h[7:6] = 10, then Freq (MHz) = Spacing (MHz) x Channel + 76 MHz.

CHAN[9:0] is not updated during a seek operation. READCHAN[9:0] provides the current tuned channel and is updated during a seek operation and after a seek or tune operation completes. Channel spacing is set with the bits SPACE 05h[5:4].

The tune operation begins when the TUNE bit is set high. The STC bit is set high when the tune operation completes. The STC bit must be set low by setting the TUNE bit low before the next tune or seek may begin.

Data Fields

si470x_reg04

union si470x_reg04

System Configuration 1.

Setting STCIEN = 1 will generate a 5 ms low pulse on GPIO2 when the STC 0Ah[14] bit is set.

Setting RDSIEN = 1 will generate a 5 ms low pulse on GPIO2 when the RDSR 0Ah[15] bit is set.

Setting STCIEN = 1 and GPIO2[1:0] = 01 will generate a 5 ms low pulse on GPIO2 when the STC 0Ah[14] bit is set.

BLNDADJ value	Description
0	31–49 RSSI dBμV (default)
1	37–55 RSSI dBμV (+6 dB)
2	19–37 RSSI dBμV (–12 dB)
3	25–43 RSSI dBμV (–6 dB)

union si470x_reg05

System Configuration 2.

SEEKTH presents the logarithmic RSSI threshold for the seek operation. The Si4702/03-C19 will not validate channels with RSSI below the SEEKTH value. SEEKTH is one of multiple parameters that can be used to validate channels. For more information, see "AN284: Si4700/01 Firmware 15 Seek Adjustability and Set- tings."

BAND value	Description
0	00 = 87.5–108 MHz (USA, Europe) (Default)
1	01 = 76–108 MHz (Japan wide band)
2	10 = 76–90 MHz (Japan)
3	11 = Reserved

si470x_reg06

union si470x_reg06

System Configuration 3.

The VOLEXT bit attenuates the output by 30 dB. With the bit set to 0, the 15 volume settings adjust the volume between 0 and –28 dBFS. With the bit set to 1, the 15 volume set- tings adjust the volume between –30 and –58 dBFS.

Refer to 4.5. "Stereo Audio Processing" on page 16.

| Softmute Attenuation | Description | | 0 | 16 dB (default) | | 1 | 14 dB | | 2 | 12 dB | | 3 | 10 dB |

| Softmute Attack/Recover Rate | Description | | 0 | fastest (default) | | 1 | fast | | 2 | slow | | 3 | slowest |

si470x_reg07

union si470x_reg07

Test 1.

Setting AHIZEN maintains a dc bias of 0.5 x VIO on the LOUT and ROUT pins to pre- vent the ESD diodes from clamping to the VIO or GND rail in response to the output swing of another device.

Register 07h containing the AHIZEN bit must not be written during the powerup sequence and high-Z only takes effect when in powerdown and VIO is supplied. Bits 13:0 of register 07h must be preserved as 0x0100 while in pow- erdown and as 0x3C04 while in powerup.

The internal crystal oscillator requires an external 32.768 kHz crystal as shown in "Typical Application Schematic" on page 14.

The oscillator must be enabled before powerup (ENABLE = 1) as shown in Figure 9, “Initialization Sequence,” on page 21. It should only be disabled after powerdown (ENABLE = 0).

Bits 13:0 of register 07h must be preserved as 0x0100 while in powerdown and as 0x3C04 while in powerup. Refer to Si4702/03 Internal Crystal Oscillator Errata.

si470x_reg08

union si470x_reg08

Test 2.

If written, these bits should be read first and then written with their pre-existing val- ues. Do not write during powerup.

si470x_reg09

union si470x_reg09

Boot Configuration.

If written, these bits should be read first and then written with their pre-existing val- ues. Do not write during powerup.

Data Fields
struct si470x_reg09.refined	refined
uint16_t	raw

si470x_reg0a

union si470x_reg0a

Status RSSI.

RSSI is measured units of dBμV in 1 dB increments with a maximum of approximately 75 dBμV. Si4702/03-C19 does not report RSSI levels greater than 75 dBuV.

AFCRL is updated after a tune or seek operation completes and indicates a valid or invalid channel. During normal operation, AFCRL is updated to reflect changing RF envi- ronments.

The SF/BL flag is set high when SKMODE 02h[10] = 0 and the seek operation fails to find a channel qualified as valid according to the seek parameters.

The SF/BL flag is set high when SKMODE 02h[10] = 1 and the upper or lower band limit has been reached. The SEEK 02h[8] bit must be set low to clear SF/BL.

The seek/tune complete flag is set when the seek or tune operation completes. Setting the SEEK 02h[8] or TUNE 03h[15] bit low will clear STC.

RDS Block A Errors	Description
0	0 errors requiring correction
1	1–2 errors requiring correction
2	3–5 errors requiring correction
3	6+ errors or error in checkword, correction not possible

Data Fields
struct si470x_reg0a.refined	refined

si470x_reg0b

union si470x_reg0b

Read Channel.

If BAND 05h[7:6] = 00, then Freq (MHz) = Spacing (MHz) x Channel + 87.5 MHz. If BAND 05h[7:6] = 01, BAND 05h[7:6] = 10, then Freq (MHz) = Spacing (MHz) x Channel + 76 MHz.

READCHAN[9:0] provides the current tuned channel and is updated during a seek operation and after a seek or tune operation completes. Spacing and channel are set with the bits SPACE 05h[5:4] and CHAN 03h[9:0].

RDS block Errors	Description
0	0 errors requiring correction
1	1–2 errors requiring correction
2	3–5 errors requiring correction
3	6+ errors or error in checkword, correction not possible

si470x_rds_blockb

union si470x_rds_blockb

RDS Block B data type.

For GCC on System-V ABI on 386-compatible (32-bit processors), the following stands:

1) Bit-fields are allocated from right to left (least to most significant). 2) A bit-field must entirely reside in a storage unit appropriate for its declared type. Thus a bit-field never crosses its unit boundary. 3) Bit-fields may share a storage unit with other struct/union members, including members that are not bit-fields. Of course, struct members occupy different parts of the storage unit. 4) Unnamed bit-fields' types do not affect the alignment of a structure or union, although individual bit-fields' member offsets obey the alignment constraints.

ATTENTION: To make it compatible with 8, 16 and 32 bits platforms and avoid Crosses boundary, it was necessary to use uint32_t data type.
