6.4.3 Single Monochrome 8-Bit Panel Timing
Figure 6-19 Single Monochrome 8-Bit Panel Timing
VDP = Vertical Display Period
= (REG[1Dh] bits 1:0, REG[1Ch] bits 7:0) + 1 Lines
VNDP = Vertical Non-Display Period
= VT - VDP
= (REG[19h] bits 1:0, REG[18h] bits 7:0) - (REG[1Dh] bits 1:0, REG[1Ch] bits 7:0) Lines
HDP = Horizontal Display Period
= ((REG[14h] bits 6:0) + 1) x 8Ts
HNDP = Horizontal Non-Display Period
= HT - HDP
= (((REG[12h] bits 6:0) + 1) x 8Ts) - (((REG[14h] bits 6:0) + 1) x 8Ts)
