4.3.11 Peripheral I/O redirection register 2 (PIOR2)

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

PIOR2 enables or disables redirection of the timer array unit functions; that is, it specifies which I/O port is assigned to

each input pin of timer array unit 1.

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

Reset signal generation clears this register to 00H.
