Set the IICSEL bit in the PMR register to 0 (select clock synchronous serial I/O with chip select function) to use
the clock synchronous serial I/O with chip select function.
After waiting three instructions or more after writing to the registers associated with clock synchronous serial I/
O with chip select (00B8h to 00BFh) or four cycles or more after writing to them, read the registers.
Set the SOOS bit in the SSMR2 register to 0 (CMOS output) in the following settings:
Do not use the SSI01 pin with NMOS open drain output for the above settings.
An example of waiting three instructions or more
An example of waiting four cycles or more
SSUMS bit in SSMR2 register = 1 (4-wire bus communication mode)
BIDE bit in SSMR2 register = 0 (standard mode)
MSS bit in SSCRH register = 0 (operate as slave device)
SSISEL bit in PMR register = 1 (use P1_6 pin for SSI01 pin)
