Input buffers are Schmitt Triggers when in I/O mode and TTL buffers when in System Bus or Parallel Slave
Port mode.
Valid only for PIC18F8525/8621 devices when ECCPMX is not set. The alternate assignments for
P1B/P1C/P3B/P3C in all PIC18F6525/6621 devices and in PIC18F8525/8621 devices when ECCPMX is
set are RE6, RE5, RE4 and RE3, respectively.
This register is unused on PIC18F6525/6621 devices and reads as ‘0’.
