Port L Control Register (PLCR) is a 16-bit read/write register that selects the pin functions. PLCR
is initialized to H'0000 by power-on resets; however, it is not initialized by manual resets, in
standby mode, or in sleep mode.
Bits 15, 14: PL7 Mode 1, 0 (PL7MD1, PL7MD0)
Bits 13, 12: PL6 Mode 1, 0 (PL6MD1, PL6MD0)
Bits 11, 10: PL5 Mode 1, 0 (PL5MD1, PL5MD0)
Bits 9, 8: PL4 Mode 1, 0 (PL4MD1, PL4MD0)
Bits 7, 6: PL3 Mode 1, 0 (PL3MD1, PL3MD0)
Bits 5, 4: PL2 Mode 1, 0 (PL2MD1, PL2MD0)
Bits 3 to 0: Reserved
These bits select the pin functions and the input pullup MOS control.

When the DA0 and DA1 pins are used as the D/A converter outputs or when PTL7 and PTL6 are
used as the other function states, PLCR should remain at its initial value.
