PWMCLK
These controls configure various PWMCLK settings.
The PWMCLK is the internal clock used by the Pulse
Width Modulator for output to the panel.
Enable
When this box is checked, the PWMCLK circuitry is
enabled.
Force High
The signal PWMOUT is forced high when this box is
checked. PWMOUT is forced low when this box is not
checked and Enable is not checked
Source
Selects the PWMCLK source. Possible sources include
CLKI and CLKI2.
Divide
Specifies the divide ratio for the clock source signal.
The divide ratio is applied to the PWMCLK source to
derive PWMCLK.
Timing
This field shows the actual PWMCLK frequency used
by the configuration process.
Duty Cycle
Selects the number of cycles that PWMOUT is high out
of 256 clock periods.
Contrast Voltage Pulse
These controls configure various Contrast Voltage
(CV) Pulse settings. The CV Pulse is provided for
panels which support the contrast voltage function.
Enable
When this box is checked, the CV Pulse circuitry is
enabled.
Force High
The signal CVOUT is forced high when this box is
checked. CVOUT is forced low when this box is not
checked and CVOUT is not enabled.
Source
The CV Pulse uses the same source clock as the
PWMCLK.
Divide
Specifies the divide ratio for the clock source signal.
The divide ratio is applied to the CVOUT Pulse clock
source to derive the CV Pulse clock frequency.
Timing
This field shows the actual CV Pulse frequency used by
the configuration process.
Burst Length
The number of pulses generated in a single CV Pulse
burst.
