TECHNOLOGY

All these measurements commence at the following VFLB pulse after enabling VMEN bit, complete the meas-

urement after one vertical frame, so minimum delay 2 vertical frame time after enabling VMEN bit is needed to

read out the measurement data. The horizontal measurement for R,G,BIN will store the minimum start loca-

tion and the maximum ending location in one vertical frame into registers. All of the input signals for timing

measurement are polarity programmable, so the different phase measurement can be obtained.

Auto sizing video measurement data bytes : read only registers

b1 ~ b0 : The most significant 2 bits of Dhrgbsta which represents the distance between the first active edge

of R,G,BIN input and reference HFLB leading edge. See Figure 10.

b7 ~ b0 : The least significant 8 bits of Dhrgbsta which represents the distance between the first active edge

of R,G,BIN input and reference HFLB leading edge. See Figure 10.

b1 ~ b0 : The most significant 2 bits of Dhrgbend which represents the distance between the last active edge

of R,G,BIN input and reference HFLB leading edge. See Figure 10.

b7 ~ b0 : The least significant 8 bits of Dhrgbend which represents the distance between the last active edge

of R,G,BIN input and reference HFLB leading edge. See Figure 10.

b2 ~ b0 : The most significant 3 bits of Dvrgbsta which represents the H line distance between the first active

line of R,G,BIN input and reference VFLB leading edge. See Figure 10.

b7 ~ b0 : The least significant 8 bits of Dvrgbsta which represents the H line distance between the first active

line of R,G,BIN input and reference VFLB leading edge. See Figure 10.
