Signal DescriptionMPC5566 Microcontroller Reference Manual, Rev. 22-34 Freescale Semiconductor2.3.9.2 eTPU A Channel / eTPU A Output Channel / GPIOETPUA[0]_ETPUA[12]_GPIO[114]ETPUA[0]_ETPUA[12]_GPIO[114] is an input/output channel pin for the eTPU A module. ETPUA[0] isthe primary function and is an input/output channel for the eTPU A module. The alternate function,ETPUA[12], is an output channel for the eTPU A module. When configured as ETPUA[12], the pinfunctions as output only. ETPUA[12] is an alternate function and is only for eTPU A module outputchannels.2.3.9.3 eTPU A Channel / eTPU A Output Channel / GPIOETPUA[1]_ETPUA[13]_GPIO[115]ETPUA[1]_ETPUA[13]_GPIO[115] is an input/output channel pin for the eTPU A module. ETPUA[1] isthe primary function and is an input/output channel for the eTPU A module. The alternate function,ETPUA[13], is an output channel for the eTPU A module. When configured as ETPUA[13], the pinfunctions as output only.2.3.9.4 eTPU A Channel / eTPU A Output Channel / GPIOETPUA[2]_ETPUA[14]_GPIO[116]ETPUA[2]_ETPUA[14]_GPIO[116] is an input/output channel pin for theeTPU A module. ETPUA[2] is the primary function and is an input/output channel for the eTPU A module.The alternate function is an output channel for the eTPU A module. When configured as ETPUA[14], thepin functions as output only.2.3.9.5 eTPU A Channel / eTPU A Output Channel / GPIOETPUA[3]_ETPUA[15]_GPIO[117]ETPUA[3]_ETPUA[15]_GPIO[117] is an input/output channel pin for the eTPU A module. ETPUA[3] isthe primary function and is an input/output channel for the eTPU A module. The alternate function is anoutput channel for the eTPU A module. When configured as ETPUA[15], the pin functions as output only.2.3.9.6 eTPU A Channel / eTPU A Output Channel / GPIOETPUA[4]_ETPUA[16]_GPIO[118]ETPUA[4]_ETPUA[16]_GPIO[118] is an input/output channel pin for the eTPU A module. The alternatefunction, ETPUA[16], is an output channel for the eTPU A module. When configured as ETPUA[16], thepin functions as output only.2.3.9.7 eTPU A Channel / eTPU A Output Channel / GPIOETPUA[5]_ETPUA[17]_GPIO[119]ETPUA[5]_ETPUA[17]_GPIO[119] is an input/output channel pin for the eTPU A module. The alternatefunction, ETPUA[17], is an output channel for the eTPU A module. When configured as ETPUA[17], thepin functions as output only.
