3-bit value. Selects the configuration of the counter prescaler module. The PWMPS field decoding is listed below.

This bit defines the polarity of the PWM output signal. If set to one, the output pulses are high level (the output will be high when-
ever the value in the counter is less than the value CVAL) If set to zero, the output pulses are low level.

PWM compare value. Used to adjust the analog value obtained after an external filter to control the contrast of the display.
