PRODUCTION DATA
The SPI communication uses a standard SPI interface. Physically the digital interface pins are nCS (Chip Select Not), SDI (SPI Data In), SDO (SPI Data Out) and CLK (SPI Clock). Each SPI transaction is initiated by a seven bit address with a R/W bit.
The SPI data input data on SDI is sampled on the low to high edge of CLK. The SPI output data on SDO is changed on the high to low edge of CLK.
See Figure 8-50 and Figure 8-51 for read and write method.
