2.4 eTPU Pin Connections and Serialization
2.4.1 ETPUA[0:15]
The ETPUA[0:15] module channels connect to external pins or can be serialized out through the DSPI C
module. The full list of connections is given in Table 2-4. Although not shown in Figure 2-4, the output
channels of ETPUA[12:15] are connected to the ETPUA[0:3]_ETPUA[12:15]_GPIO[114:117] pins.
The eTPU TCRA clock input is connected to an external pin only.
A diagram for the ETPUA[0:15] to SOUTC connection is given in Figure 2-4.
