Pad Configuration Registers 127–129 (SIU_PCR127–SIU_PCR129)
The SIU_PCR127–SIU_PCR129 registers control the function, direction, and electrical attributes of
ETPUA[13:15]_PCSB[3:5]_GPIO[127:129].

OBE

1
When configured as PCSB[3:5], the OBE bit has no effect. The OBE bit must be set to 1 for ETPUA[13:15] or GPIO[127:129]
when configured as outputs.
IBE

2
The IBE bit must be set to 1 for ETPUA[13:15], PSCB[3:5], or GPIO[127:129] when configured as inputs. When configured as
output, set the IBE bit to 1 to show the pin state in the GPDI register.
