Datasheet KT0803L (KT Micro) - 7

KT0803L 4 Register Bank
The register bank stores channel frequency codes, calibration parameters, operation status, mode and power controls, which can be accessed by the internal digital controller, state machines and external micro controllers through the serial interface. All registers are 8 bits wide. Control logics are active high unless specifically noted.
