Switching between the function for fixed-value output and function for control of the PL022
A function has been added to set the Chip Select signal (High/Low) by register control. You can
switch between Chip Select control by the register and Chip Select control by the PL022.
In Chip Select control by the register, the Chip Select does not change every 8 bits or 16 bits
during the communication, and fixed values can be output during the communication.
Transfer Rate
The maximum transfer rate of the SPI is determined by the combination of the clock selected as the clock source
(SYSPLL, XOSC, RCOSC, or RTC), the X'tal Oscillator clock, and the voltage mode (High Performance mode/
Low Power mode). The following tables show each combination and the maximum transfer rates.
