lower panel individually.
The LPP field specifies the number of active lines per LCD panel.
The actual value counted is the value set in this field incremented by one. Therefore, 1 to
1024 lines can be specified.

• Number of lines per panel (LPP)
• Vertical sync pulse width (VSW)
• Vertical front porch (VFP) period
• Vertical back porch (VBP) period
LCDTiming1 is the register to control the following:
Vertical back porch refers to the number of non-active lines at the start of each frame
Vertical front porch refers to the number of non-active lines at the end of each frame
Vertical sync pulse width refers to the number of horizontal sync lines. For STN displays,
For dual-panel displays, this field should be programmed for the upper panel and the
