2.3.9.31 eTPU B TCR Clock / External Interrupt Request / GPIO
TCRCLKB_IRQ
[6]_GPIO[146]
TCRCLKB_IRQ[6]_GPIO[146] is the TCR B clock input for the eTPU module. The alternate function is
an external interrupt request input for the SIU module.
2.3.9.32 eTPU B Channel / eTPU B Output Channel / GPIO
ETPUB[0:15]_ETPUB[16:31]_GPIO[147:162]
ETPUB[0:15]_ETPUB[16:31]_GPIO[147:162] are 16 input/output channel pins for the eTPU B module.
The alternate functions are output channels for the eTPU B module; that is, when configured as
ETPUB[16:31], the pins function as outputs only.
2.3.9.33 eTPU B Channel / DSPI A / GPIO
ETPUB[16:19]_PCSA[1:4]_GPIO[163:166]
ETPUB[16:19]_PCSA[1:4]_GPIO[163:166] are input/output channel pins for the eTPU B module. The
alternate functions are peripheral chip select signals for DSPI A.
2.3.9.34 eTPU B Channel / GPIO
ETPUB[20:31]_GPIO[167:178]
ETPUB[20:31]_GPIO[167:178] are input/output channel pins for the eTPU B module.
2.3.10 Enhanced Management Input/Output System (eMIOS) Signals
2.3.10.1 eMIOS Channel / eTPU A Output Channel / GPIO
EMIOS[0:9]_ETPUA[0:9]_GPIO[179:188]
EMIOS[0:9]_ETPUA[0:9]_GPIO[179:188] is an input/output channel pin for the eMIOS module. The
alternate functions are output channels for the eTPU A module; that is, when configured as ETPUA[0:9],
the pins function as outputs only.
2.3.10.2 eMIOS Channel / DSPI D / GPIO
EMIOS[10:11]_PCSD[3:4]_GPIO[189:190]
EMIOS[10:11]_PCSD[3:4]_GPIO[189:190] is an input/output channel pin for the eMIOS module. The
alternate functions are PCSD[3:4] and are peripheral chip selects for the DSPI D module.
2.3.10.3 eMIOS Output Channel / DSPI C / GPIO
EMIOS[12]_SOUTC_GPIO[191]
EMIOS[12]_SOUTC_GPIO[191] is an output channel pin for the eMIOS module. The alternate function
is the data output signal for the DSPI C module.
