Only channel 0 can be enabled in peripheral mode.
Figure 12-188 shows an example of four peripherals wired on a single controller device.
Channel 0 in peripheral mode has the following resources:
The MCSPI_TX_1/2/3 and MCSPI_RX_1/2/3 registers are not used. Reading from or writing to a channel register other than channel 0 has no effect.
The SPICLK frequency of a transfer is controlled by the external MCSPI controller connected to the MCSPI peripheral device. The MCSPI_CHCONF_0[5-2] CLKD bit field is not used in peripheral mode.
The configuration of the channel can be loaded in the MCSPI_CHCONF_0 only when the channel is disabled.
