Detailed Description

KT0915 Defined Data Types

Defined Data Types is a way to represent the KT0915 registers information

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

The information shown here was extracted from Datasheet:

KT0915 stereo FM / TV / MW / SW / LW 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
