20.3.24 Port L Control Registers H and L (PLCRH, PLCRL)
Port L control registers H and L (PLCRH, PLCRL) are 16-bit readable/writable registers that
select the functions of the 14 multiplex pins in port L. PLCRH selects the functions of the pins for
the upper 6 bits of port L, and PLCRL selects the functions of the pins for the lower 8 bits.
PLCRH and PLCRL are initialized to H'0000 by a power-on reset (excluding a WDT power-on
reset), and in hardware standby mode. They are not initialized in software standby mode or sleep
mode.

• Bits 15 to 12—Reserved: These bits are always read as 0. The write value should always be 0.
• Bits 11 and 10—PL13 Mode Bits 1 and 0 (PL13MD1, PL13MD0): These bits select the
function of pin PL13/IRQOUT.
