Terminal Configuration and Functions

4.3.11 UART

NOTE

For more information see the Serial Communication Interface UART section of the device

TRM.

CAUTION

The IO timings provided in Section 5.9, Timing Requirements and Switching

Characteristics are only valid if signals within a single IOSET are used. The

IOSETs are defined in Table 5-39.

4.3.12 McSPI

NOTE

For more information, see the Serial Communication Interface / Multichannel Serial

Peripheral Interface (McSPI) section of the device TRM.

CAUTION

The IO timings provided in Section 5.9, Timing Requirements and Switching

Characteristics are applicable for all combinations of signals for SPI2, SPI3 and

SPI4. However, the timings are only valid for SPI1 if signals within a single

IOSET are used. The IOSETS are defined in the Table 5-42.
