Refer to Table 6-19 for bit field definitions. Table 6-54 lists the PA fields for
CNRXC_PCSD[4]_GPIO[88].
6.3.1.55 Pad Configuration Register 89 (SIU_PCR89)
The SIU_PCR89 register controls the function, direction, and electrical attributes of TXDA_GPIO[89].

1
When configured as TXDA, the OBE bit has no effect. When configured as GPDO, set the OBE bit to 1.
IBE
2
2
When the pad is configured as an output, set the IBE bit to 1 to show the pin state in the GPDI register.
Clear the IBE bit to 0 to reduce power consumption. When configured for eSCI loop back operation or GPDI,
set the IBE bit to 1.
