commands used to specify the contrast levels for the
gray scale, 4 levels available. The relationship between
gray mode and data in RAM is as follow:
Set PWM and FRC for gray-scale operation.
FRC = 0: 4-frames (POR)
FRC = 1: 3-frames
PWM = 00: 9-levels (POR)
PWM = 01: 9-levels
PWM = 10: 12-levels
PWM = 11: 15-levels
