2.4.2 ETPUA[16:31]
ETPUA[16:23,30:31] connect to external pins for both the input and output function.
ETPUA[16:21,24:29] are serialized out on the DSPI B and DSPI D modules and ETPUA[22:23,30:31] are
not serialized out. ETPUA[24:29] connect to external pins for only the output function.
Figure 2-5 shows
the connections for ETPUA16 and applies to ETPUA[16:21]. Figure 2-6 shows the connections for
ETPUA24 and applies to TPUA[24:29]. The full ETPUA to DSPI B connections are given in Table 2-5 ,
and ETPU A to DSPI D in Table 2-6 . Although not shown in Figure 2-5 , the output channels of
ETPUA[16:23] are also connected to the ETPUA[4:11]_ETPUA[16:23]_GPIO[118:125] pins.
