The port L control register (PLCR) is a 16-bit readable/writable register that selects the pin
functions. PLCR is initialized to H'0000 by a power-on reset, but is not initialized by a manual
reset, in standby mode, or in sleep mode.
Bits 15 and 14âPL7 Mode 1 and 0 (PL7MD1, PL7MD0)
Bits 13 and 12âPL6 Mode 1 and 0 (PL6MD1, PL6MD0)
Bits 11 and 10âPL5 Mode 1 and 0 (PL5MD1, PL5MD0)
Bits 9 and 8âPL4 Mode 1 and 0 (PL4MD1, PL4MD0)
Bits 7 and 6âPL3 Mode 1 and 0 (PL3MD1, PL3MD0)
Bits 5 and 4âPL2 Mode 1 and 0 (PL2MD1, PL2MD0)
Bits 3 and 2âPL1 Mode 1 and 0 (PL1MD1, PL1MD0)
Bits 1 and 0âPL0 Mode 1 and 0 (PL0MD1, PL0MD0)
These bits select the pin functions and perform input pull-up MOS control.

When the DA0 and DA1 pins are used as the D/A converter outputs or when PTL7 and PTL6 are
used in the âother functionâ state, PLCR should by kept at its initial value.
