FPLINE Start Position
These bits are used in TFT/D-TFD mode to specify the position of the FPLINE pulse.
These bits specify the delay, in 8-pixel resolution, from the end of a line of display data
(FPDAT) to the leading edge of FPLINE. This register is effective in TFT/D-TFD mode
only (REG[01h] bit 7 = 1). This register is programmed as follows:
The following constraint must be satisfied:
Horizontal Non-Display Period
These bits specify the horizontal non-display period in 8-pixel resolution.
FPFRAME Start Position
These bits are used in TFT/D-TFD mode to specify the position of the FPFRAME pulse.
These bits specify the number of lines between the last line of display data (FPDAT) and
the leading edge of FPFRAME. This register is effective in TFT/D-TFD mode only
(REG[01h] bit 7 = 1).
The contents of this register must be greater than zero and less than or equal to the Vertical
Non-Display Period Register, i.e.
