Number
1 Line pulse to frame signal
2 Line pulse width
3 LCLK to data valid
4 Shift clock to line pulse
Note:
The preceding data is measured by summing the polarity bits LFLM, LLP, and LCLK in the POLCF register.
The variable pixclk = LCD_CLK / (pcd + 1).
The self-refresh mode timing between LFRM, LSCLK, LD, and LLP are the same as in normal mode.
The self-refresh mode is entered and exited on the positive edge of LFRM.
In self-refresh mode, the LFRM and LLP waveforms are identical to the waveforms in normal mode, while LD and
LCLK remain in inactive level.
