2.3.11 eMIOS Signals
2.3.11.1 eMIOS Channel / eTPU A Channel (Output Only) / GPIO
EMIOS[0:9]_ETPUA[0:9]_GPIO[179:188]
EMIOS[0:9]_ETPUA[0:9]_GPIO[179:188] are input and output channel pins for the eMIOS module. The
alternate functions are for the eTPU A module output channels only. These pins can be used as GPIO
signals.
2.3.11.2 eMIOS Channel / GPIO
EMIOS[10:11]_GPIO[189:190]
EMIOS[10:11]_GPIO[189:190] are input and output channel pins for the eMIOS module. These pins can
be used as GPIO signals.
2.3.11.3 eMIOS Channel (Output Only) / DSPI C Data Output / GPIO
EMIOS[12]_SOUTC_GPIO[191]
EMIOS[12]_SOUTC_GPIO[191] has a primary signal function for the eMIOS module output channel.
The alternate function is the data output for the DSPI C module. This pin can be used as a GPIO signal.
2.3.11.4 eMIOS Channel (Output Only) / DSPI D Data Output / GPIO
EMIOS[13]_SOUTD_GPIO[192]
EMIOS[13]_SOUTD_GPIO[192] has a primary signal function for the eMIOS module output channel.
The alternate function is the data output for the DSPI D module. This pin can be used as a GPIO signal.
2.3.11.5 eMIOS Channel (Output Only) / External Interrupt Request / GPIO
EMIOS[14:15]_IRQ
[0:1]_GPIO[193:194]
EMIOS[14:15]_IRQ[0:1]_GPIO[193:194] has primary signal functions for the eMIOS module output
channels. The alternate function is for external interrupt request inputs. These pins can be used as GPIO
signals.
2.3.11.6 eMIOS Channel / eTPU Channel (Output Only) / GPIO
EMIOS[16:23]_ETPUB[0:7]_GPIO[195:202]
EMIOS[16:23]_ETPUB[0:7]_GPIO[195:202] has primary signal functions for the eMIOS module output
channels. The alternate functions, ETPUB[0:7], are only available on the MPC5554. ETPUB[0:7] signals
are for the eTPU B module for output channels only. These pins can be used as GPIO signals.
2.3.12 GPIO Signals
2.3.12.1 GPIO
EMIOS[14:15]_GPIO[203:204]
The EMIOS[14:15]_GPIO[203:204] pins’ primary function is EMIOS[14:15]. When configured as
EMIOS[14:15], the balls function as output channels for the eMIOS module. Because other balls already
