HSLEN<7:0>: HSYNC Pulse-Width Configuration bits (in DISPCLKs)
DPHSOE bit (G1CON3<0>) must be set for the HSYNC signal to toggle; minimum value is 1.
HSST<7:0>: HSYNC Start Delay Configuration bits (in DISPCLKs)
This is the number of DISPCLK cycles from the start of horizontal blanking to the start of HSYNC active.
ACTLINE<7:0>: Number of Lines Before the First Active (Displayed) Line bits
Typically, ACTLINEx = VENSTx (G1DBLCON<15:8>).
This register is added for versatility in the timing of the active lines.
For TFT mode, DPMODE bits (G1CON2<2:0>) = 001; the minimum value is 2.
For STN mode, DPMODE bits (G1CON2<2:0>) = 010,011,100; the minimum value is 0.
ACTPIX<7:0>: Number of Pixels Before the First Active (Displayed) Pixel bits (in DISPCLKs)
Typically, ACTPIXx = HENSTx (G1DBLCON<7:0>).
This register is added for versatility in the timing of the active pixels. Note that the programmed value
is computed in DISPCLK cycles. This value is dependent on the DPGWDTH bit (G1CON2<15:14>).
Refer to the “PIC24F Family Reference Manual”, Section 43. “Graphics Controller Module (GFX)”
for details.
