Bits 15:8 – PWMCVAL[7:0] LCD Controller PWM Compare Value
PWM compare value. Used to adjust the analog value obtained after an external filter to control the contrast of the display.
Bit 4 – PWMPOL LCD Controller PWM Signal Polarity
This bit defines the polarity of the PWM output signal.
Value | Description |
---|---|
0 | The output pulses are low level. |
1 | The output pulses are high level (the output is high whenever the value in the counter is less than value CVAL). |
Bits 2:0 – PWMPS[2:0] PWM Clock Prescaler
Selects the configuration of the counter prescaler module.
Value | Name | Description |
---|---|---|
000 | DIV_1 | The counter advances at a rate of fCOUNTER = fPWM_SELECTED_CLOCK |
001 | DIV_2 | The counter advances at a rate of fCOUNTER = fPWM_SELECTED_CLOCK/2 |
010 | DIV_4 | The counter advances at a rate of fCOUNTER = fPWM_SELECTED_CLOCK/4 |
011 | DIV_8 | The counter advances at a rate of fCOUNTER = fPWM_SELECTED_CLOCK/8 |
100 | DIV_16 | The counter advances at a rate of fCOUNTER = fPWM_SELECTED_CLOCK/16 |
101 | DIV_32 | The counter advances at a of rate fCOUNTER = fPWM_SELECTED_CLOCK/32 |
110 | DIV_64 | The counter advances at a of rate fCOUNTER = fPWM_SELECTED_CLOCK/64 |
