Setup and configuration
Both serial controllers, SC1 and SC2, support SPI slave mode. SPI slave mode is enabled
by the following register settings:
●
●
The SPI slave controller receives its clock from an external SPI master device and supports
rates up to 5 Mbps.
The SPI slave controller supports various frame formats depending upon the clock polarity
(SC_SPIPOL), clock phase (SC_SPIPHA), and direction of data (SC_SPIORD) (see Table 8
6). The SC_SPIPOL, SC_SPIPHA, and SC_SPIORD bits are defined within the
SCx_SPICFG registers.
