Port B I/O Registers H and L (PBIORH and PBIORL)
PBIORH and PBIORL are 16-bit readable/writable registers that select the I/O direction for the
port B pins. Bits PB31IOR to PB0IOR correspond to pins PB31 to PB0, respectively. PBIORH
and PBIORL are enabled when the function of the port B pins is set to general-purpose I/O (PB31
to PB0) and to TIOC I/O (MTU2) by PBCR, and are disabled in other cases. When a bit in
PBIORH and PBIORL is set to 1, the corresponding pin is set to output, and when set to 0, the pin
is set to input.
PBIORH and PBIORL are initialized to H'0000 by a power-on reset or by switching to deep
standby mode. These registers are not initialized either by a manual reset or by switching to sleep
mode or software standby mode.
