The port K invert register (PKIR) is a 16-bit readable/writable register that sets the port K
inversion function. Bits PK15IR to PK0IR correspond to pins PK15/TO8P to PK0/TO8A. PKIR is
enabled when port K pins function as ATU outputs, and disabled otherwise.
When port K pins function as ATU outputs, the value of a pin is inverted when the corresponding
bit in PKIR is set to 1.
PKIR is initialized to H'0000 by a power-on reset (excluding a WDT power-on reset), and in
hardware standby mode. It is not initialized in software standby mode or sleep mode.
