Document overview
This programming guide has been restructured from previous revisions for clarity. This contains two
documents for interface and programmer separately. Interface document contains I2C interface, 3 wire SPI
interface and 4 wire SPI interface .Programmer document contains a complete programming guide for using
any interface.

2 Three- wire SPI interface
RDA1846 enable software programming through three-wire(SPI) interface. Software controls chip working
states, such as Txon or Rxon operation, and reads status register to get operation result through three-wire
interface.
Three-wire interface is slave interface. It includes three pins: SEN , SCLK and SDIO. SEN and SCLK are
input pins , SDIO are bi-direction pins.
RDA1846 samples command byte and data at posedge of SCLK.The turn around cycle between command byte
from MCU and data from RDA1846 is a half cycle. RDA1846 samples command byte at posedge of SCLK,
and output data also at posedge of SCLK.
