LLINE Pulse Start Position Bits [9:0]
These bits specify the start position of the horizontal sync signal, in number of PCLK.
The maximum allowed value of LLINE Pulse Start Position Bits is 3FEh.
LLINE Pulses Start Position in PCLK = Bits [9:0] + 1
Note
For panel AC timing and timing parameter definitions, see Section10.4 “Display Interface”.

LFRAME Pulse Polarity
This bit selects the polarity of the vertical sync signal. The vertical sync signal is
typically named as LFRAME or SPS, depending on the panel typeWhen this bit = 0,
the vertical sync signal is active low.
When this bit = 1, the vertical sync signal is active high.
LFRAME Pulse Width Bits [2:0]
These bits specify the width of the panel vertical sync signal, in 1 line resolution. The
vertical sync signal is typically named as LFRAME or SPS, depending on the panel
type. The maximum allowed value of LFRAME Pulse Width Bits is 6.
Bits 2-0
LFRAME Pulse Width in number of pixels = (Bits [2:0] + 1) x Horizontal Total + offset
Note
For panel AC timing and timing parameter definitions, see Section 10.4 “Display Interface”.
