6.3.1.80 Pad Configuration Register 118 (SIU_PCR118)
The SIU_PCR118 registers control the function, direction, and electrical attributes of
ETPUA[4]_ETPUA[16]_GPIO[118]. Only the output channel of ETPUA[16] is connected. Both the input
and output channels of ETPUA[4] are connected.

Refer to Table 6-19 for bit field definitions. Table 6-80 lists the PA fields for
ETPUA[4]_ETPUA[16]_GPIO[118].
6.3.1.81 Pad Configuration Register 119 (SIU_PCR119)
The SIU_PCR119 registers control the function, direction, and electrical attributes of
ETPUA[5]_ETPUA[17]_GPIO[119]. Only the output channels of ETPUA[17] are connected. Both the
input and output channels of ETPUA[5] are connected.

1
The OBE bit must be set to 1 for ETPUA[4], ETPUA[16] and GPIO[118] when configured as outputs.
When configured as ETPUA[16] the OBE bit has no effect.
IBE

2
The IBE bit must be set to 1 for ETPUA[4], ETPUA[16] and GPIO[118] when configured as inputs. When the pad is configured
as an output, set the IBE bit to 1 to show the pin state in the GPDI register.
