= (REG[09h] bits [1:0], REG[08h] bits [7:0]) + 1
= (REG[0Ah] bits [5:0]) + 1
= ((REG[04h] bits [6:0]) + 1)*8Ts
= HNDP1 + HNDP2 = ((REG[05h] bits [4:0]) + 1)*8Ts
Note: The signals RED, GREEN and BLUE are analog signals from the embedded DAC and represent the
color components which make up each pixel.
