38.10.24 Contrast Control Register
Name: CONTRAST_CTR
Address:0x00600840
Access: Read-write
Reset value: 0x00000000
• PS
This 2-bit value selects the configuration of a counter prescaler. The meaning of each combination is as follows:
• POL
This bit defines the polarity of the output. If 1, the output pulses are high level (the output will be high whenever the value in
the counter is less than the value in the compare register CONTRAST_VAL). If 0, the output pulses are low level.
• ENA
When 1, this bit enables the operation of the PWM generator. When 0, the PWM counter is stopped.

The counter advances at a rate of fCOUNTER = fLCDC_CLOCK.
The counter advances at a rate of fCOUNTER = fLCDC_CLOCK/2.
The counter advances at a rate of fCOUNTER = fLCDC_CLOCK/4.
The counter advances at a rate of fCOUNTER = fLCDC_CLOCK/8.
