Refer to Table 6-19 for bit field definitions. Table 6-51 lists the PA fields for
CNTXB_PCSC[3]_GPIO[85].
6.3.1.52 Pad Configuration Register 86 (SIU_PCR86)
The SIU_PCR86 register controls the function, direction, and electrical attributes of
CNRXB_PCSC[4]_GPIO[86]. This register allows selection of the CNRXB,_PCSC[4], and GPIO[86]
functions.

When configured as CNRXB or PCSC[4], 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 as GPDI, set the IBE bit to 1.
