SPI Communication
4.1
Protocol and Timing
The transferred data bits via MOSI (Master Out – Slave In) and MISO (Master In – Slave Out) are defined
as follows:
A15….A00 = 16-bit register address
W15….W00 = 16-bit write data (in write mode)
X15….X00, Y15 = 16-bit read data or previous command (depending on mode)
R15…R0 = 16-bit read data in read mode or previous data in write mode
