Notes:
LEN - LCD enable:
0 - LCD is disabled.
1 - LCD is enabled.
VSP - Vertical sync polarity:
0 - Vertical sync clock is active high, inactive low.
1 - Vertical sync clock is active low, inactive high.
VSW - Vertical sync width:
1 to 64 horizontal sync clock periods to assert the vertical sync signal (hsync transitions).
HSW - Horizontal sync pulse width:
1 to 64 pixel clock periods to assert the line clock (pixel clock transitions).
HSP - Horizontal sync polarity:
0 - Horizontal sync clock is active high, inactive low.
1 - Horizontal sync clock is active low, inactive high.
BFW - Beginning-of-frame horizontal sync clock wait count:
0 to 255 horizontal sync clock periods to wait at the beginning of each frame (hsync transitions).
BLW - Beginning-of-line pixel clock wait count:
1 to 256 pixel clock periods to wait after line clock negated before asserting pixel clocks
(pixel clock transitions).
ELW - End-of-line pixel clock wait count:
1 to 256 pixel clock periods to wait after last pixel in line before asserting line clock (pixel clock
transitions).
PPL - Pixels per line:
1 to 1024 pixels per line on screen.
