Vertical Total Bits [9:0]
These bits specify the LCD panel Vertical Total period, in 1 line resolution. The Vertical
Total is the sum of the Vertical Display Period and the Vertical Non-Display Period.
The maximum Vertical Total is 1024 lines. See Figure 10-12 :
Parameters
Vertical Total in number of lines = Bits [9:0]+ 1
Note
This register must be programmed such that the following condition is fulfilled.
For panel AC timing and timing parameter definitions, see Section 10.4 “Display
Interface”.
Vertical Display Period Bits [9:0]
These bits specify the LCD panel Vertical Display period, in 1 line resolution. The
Vertical Display period should be less than the Vertical Total to allow for a sufficient
Vertical Non-Display period.
Vertical Display Period in number of lines = Bits [9:0] + 1
Note
For panel AC timing and timing parameter definitions, see Section 10.4 “Display
Interface”.
