Notes: 1. The pin also functions as an HIFEBL pin by setting the PFC registers.
2. The pin also functions as an HIF pin by setting the PFC registers.
When the HIF pin function is selected for the HIFEBL pin and this pin by setting the PFC
registers, the input and/or output buffers are controlled according to the HIFEBL pin
state.
When the HIF pin function is not selected for the HIFEBL pin and is selected for this pin
by setting the PFC registers, the input and/or output buffers are always turned off. This
setting is prohibited.
