φ CLOCK SYSTEM OUTPUT FUNCTION
The internal system clock φ or XCIN frequency signal can be out-
put from port P41 by setting the φ output control register. Set bit 1
of the port P4 direction register to “1” when outputting φ clock.

Temporary data register
The temporary data register (addresses 002C16 to 002E16) is the
8-bit register and does not have the control function. It can be
used to store data temporarily. It is initialized after reset.
RRF register
The RRF register (address 002F16)is the 8-bit register and does
not have the control function. As for the value written in this regis-
ter, high-order 4 bits and low-order 4 bits interchange. It is
initialized after reset.

Set the bit 4 in the peripheral function expansion register to “1”
when the XCIN frequency signal is output.
