6.2
The SPI module supports two (of the four) standard SPI
modes. These are Mode 0,0 and 1,1. The mode is
determined by the state of the SDI pin on the rising
edge of the 1st clock bit (of the 8-bit byte).
6.2.1
In Mode 0,0: SCK idle state = low (V
in on the SDI pin on the rising edge of SCK and clocked
out on the SDO pin on the falling edge of SCK.
6.2.2
In Mode 1,1: SCK idle state = high (V
clocked in on the SDI pin on the rising edge of SCK and
clocked out on the SDO pin on the falling edge of SCK.
