Interface (DSPI) ,” Figure 19-22 and Table 19-20 , eTPU output channel 0
(ETPUA[0]_ETPUA[12]_GPIO[114]) is serialized to DSPI C and then connected to input 2 on IMUX for
external IRQ[3]. Most eTPU channels are serialized, but eTPU channels 22 and 23 are connected only to
their pin.
Some channels are serialized through one DSPI to two different locations. The eTPU channel 29
(ETPUA[29]_PCSC[2]_GPIO[143]) is serialized to both eTPU_A input channel 29 and input 1 on IMUX
for external IRQ[8]. This serialization is performed by DSPI B. Finally, some channels are serialized
through different DSPIs. The eTPU channel 17 is serialized through DSPI B to input 1 on IMUX for
external IRQ[6], but is also serialized by DSPI D to input 3 on IMUX for external IRQ[2].
Figure 19-21 , Figure 19-22 , and Figure 19-23 along with Table 19-19 , Table 19-20 , and Table 19-21
explain the serial connectivities of the eTPU and eMIOS channels.
