The port B invert register (PBIR) is a 16-bit readable/writable register that sets the port B
inversion function. Bits PB15IR to PB13IR and PB11IR to PB0IR correspond to pins
PB15/PULS5/SCK2 to PB13/SCK0 and PB11/RxD4/HRxD0/TO8H to PB0/TO6A. PBIR is
enabled when port B pins function as ATU-II outputs or serial clock pins, and disabled otherwise.
When port B pins function as ATU-II outputs or serial clock pins, the value of a pin is inverted
when the corresponding bit in PBIR is set to 1.
PBIR 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.
