◆ rda_reg02

union rda_reg02

Register 0x02 - Basic setup: RESET configuration;.

Clock type configuration; seek operation; Sterio/Mono; Bass; and Audio configuration

The RDA5807M is RESET itself when power up. You also can use soft reset by triggering SOFT_RESET bit to 1.

Seek begins in the direction specified by SEEKUP and ends when a channel is found, or the entire band has been searched.

The SEEK bit is set low and the STC bit is set high when the seek operation completes.

RCLK NON-CALIBRATE MODE. if 0=RCLK clock is always supply; if 1=RCLK clock is not always supply when FM work ( when 1, RDA5807M can’t directly support -20 °C ~70 °C temperature.

Only suppory ±20°C temperature swing from tune point).

◆ rds_blockb

union 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.

Group RDS type 4A ( RDS Date and Time) When group type 4A is used by the station, it shall be transmitted every minute according to EN 50067. This Structure uses blocks 2,3 and 5 (B,C,D)

ATTENTION: To make it compatible with 8, 16 and 32 bits platforms and avoid Crossing boundary, it was necessary to split minute and hour representation.
