11.1.4 PWMCLK
PWMCLK is the internal clock used by the Pulse Width Modulator for output to the panel.
The source clock options for PWMCLK may be selected as in the following table.
For further information on controlling PWMCLK, see Section 7.2.9 “Pulse Width Modulation (PWM) Clock and
Contrast Voltage (CV) Pulse Configuration Registers”.
Note
The SSD1905 provides Pulse Width Modulation output on the pin LPWMOUT.
LPWMOUT can be used to control LCD panels which support PWM control of the back-light inverter.
