4.3.17 Peripheral I/O redirection register 8 (PIOR8)
This register is used to specify whether to enable or disable the peripheral I/O redirect function.
PIOR8 enables or disables redirection of the real-time clock correction clock (1 Hz) output function; that is, it specifies
which I/O port is assigned to the real-time clock correction clock (1 Hz) output pin.
This register can be set by an 8-bit memory manipulation instruction.
Bits 7 to 1 are read-only. Bit 0 can be read or written to.
After reset cancellation, this register can always be read or written to.
Any reset source clears this register to 00H.
