4.4.11 Multichannel Serial Peripheral Interface (McSPI)
CAUTION
The I/O timings provided in Section 7, Timing Requirements and Switching
Characteristics are applicable for all combinations of signals for SPI1 and SPI2.
However, the timings are valid only for SPI3 and SPI4 if signals within a single
IOSET are used. The IOSETS are defined in Table 7-42.
NOTE
For more information, see the Serial Communication Interface / Multichannel Serial
Peripheral Interface (McSPI) section of the device TRM.
