7.5.7 8-Bit Dual Monochrome Passive LCD Panel Timing

Figure 7-36: 8-Bit Dual Monochrome Passive LCD Panel Timing

VDP = Vertical Display Period = (REG[09h] bits [1:0], REG[08h] bits [7:0]) + 1
VNDP = Vertical Non-Display Period = (REG[0Ah] bits [5:0]) + 1
HDP = Horizontal Display Period = ((REG[04h] bits [6:0]) + 1)*8Ts
HNDP = Horizontal Non-Display Period = ((REG[05h] bits [4:0]) + 1)*8Ts
