Bits 10–0
This is an 11-bit wide register that records the lowest measured value of the horizontal front porch
during video detect. When no video is detected, this register should return a value of zero. Once
measurement is completed and the auto size enable bit has cleared itself back to 0, the measured
data is ready to be read by the microcontroller. Reading this register before that may give
erroneous results. This register resets to default values, ready to record new measured values
when the auto size enable bit is set again.
