Figure 7-25: 12-Bit TFT/D-TFD Panel Timing

VDP = Vertical Display Period = (REG[06h] bits 1-0, REG[05h] bits 7-0) + 1 Lines

VNDP = Vertical Non-Display Period = VNDP1 + VNDP2 = (REG[0Ah] bits 5-0) Lines

VNDP1 = Vertical Non-Display Period 1 = REG[09h] bits 5-0 Lines

VNDP2 = Vertical Non-Display Period 2 = (REG[0Ah] bits 5-0) - (REG[09Ah] bits 5-0) Lines

HDP = Horizontal Display Period = ((REG[04h] bits 6-0) + 1) x 8Ts

HNDP = Horizontal Non-Display Period = HNDP1 + HNDP2 = (REG[08h] + 4) x 8Ts

HNDP1= Horizontal Non-Displa y Period 1 = ((REG[07h] bits4-0) x 8) +1 6Ts

HNDP2= Horizontal Non-Displa y Period 2 = (((REG[08h] bits4-0 ) - (REG[07h] bits 4-0)) x 8) +16Ts
