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.

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.
