1
When configured as TXDB or PCSD[1], 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.
