The SCOMEN bit in the SCOMC register is the overall master control for the LCD driver; however
this bit is used in conjunction with the COMnEN bits to select which Port C pins are used for LCD
driving. Note that the Port Control register does not need to first setup the pins as outputs to enable the
LCD driver operation.

The LCD COM driver enables a range of selections to be provided to suit the requirement of the LCD
panel which is being used. The bias resistor choice is implemented using the ISEL1 and ISEL0 bits in
the SCOMC register.
