4.3.13 Peripheral I/O redirection register 4 (PIOR4)

This register is used to specify whether to enable or disable the peripheral I/O redirect function.

PIOR4 enables or disables redirection of the serial communication functions; that is, it specifies which I/O port is

assigned to each serial data I/O pin of CAN, serial data I/O pin of LIN, serial data I/O pin of the serial array unit, clock

I/O pin, and slave select input pin.

This register can be set by an 8-bit memory manipulation instruction.

Reset signal generation clears this register to 00H.
