ST7LITE49K2
Bit 2 = CPHA Clock phase.
Bits 1:0 = SPR[1:0] Serial clock frequency.
Table 52.
This bit is set and cleared by software.
0: The first clock transition is the first data capture edge.
1: The second clock transition is the first capture edge.
The slave must have the same CPOL and CPHA settings as the master.
These bits are set and cleared by software. Used with the SPR2 bit, they select the
baud rate of the SPI serial clock SCK output by the SPI in master mode.
These 2 bits have no effect in slave mode.
