Refer to Table 6-19 for bit field definitions. Table 6-64 lists the PA fields for PCSA[2]_SCKD_GPIO[98].
6.3.1.65 Pad Configuration Register 99 (SIU_PCR99)
The SIU_PCR99 register controls the function, direction, and electrical attributes of
PCSA[3]_SIND_GPIO[99]. This register allows selection of the PCSA[3], SIND and GPIO functions.

When configured as PCSA[3] or SIND, the OBE bit has no effect. When configured as GPDO, set the OBE bit to 1.
IBE

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 as GPDI, set the IBE bit to 1.
