Signal Description
The pins used for interfacing the compliant external devices may be multiplexed with PIO lines.
The programmer must first program the PIO controllers to assign the SPI pins to their peripheral
functions.
Table 29-2.
The SPI may be clocked through the Power Management Controller (PMC), thus the program-
mer must first configure the PMC to enable the SPI clock.
