ETECTION OF ACQUISITION POSITION
MUXB/MUXA are filled with current counter values of
CNT_B/CNT_A (horizontal and vertical acquisition
position) by a positive edge of VI1 or using ‘SAMPLE AQUI
and DISPL’ register. Thus, it is possible to detect the
location of VI1 within one line by reading MUXB (CNT_B)
after VI1 has occurred.

MUXC
bit 4:
9th-bit (MSB) of sampled CNT_B.
MUXF/MUXG are filled with current counter values of
CNT_A (horizontal acquisition position) if positive/negative
edge of PIP signal occurs.
address XXXX 1000 (08H)
MUXF
sampled CNT_A
value by rising PIP edge
address XXXX 1100 (0CH)
MUXG
