2.11.40 GPIO Input 2 Register
Subaddress 41h
Read only
7 6 5 4 3 2 1 0
GPIO AVID GLCO VS HS FID C_9 C_8
GPIO input terminal status:
0 = Input is a low.
1 = Input is a high.
AVID input terminal status:
0 = Input is a low.
1 = Input is a high.
GLCO input terminal status:
0 = Input is a low.
1 = Input is a high.
VS input terminal status:
0 = Input is a low.
1 = Input is a high.
HS input status:
0 = Input is a low.
1 = Input is a high.
FID input status:
0 = Input is a low.
1 = Input is a high.
C_x input status:
0 = Input is a low.
1 = Input is a high.
These status bits are only valid when terminals are used as input and its states updated at every line.
2.11.41 Vertical Line Count Register
Subaddress 42h−43h
Read only
Subaddress 7 6 5 4 3 2 1 0
42h Vertical line [7:0]
43h Reserved Vertical line [9:8]
Vertical line [9:0] represents the detected total number of lines from the previous frame. This can be used with
nonstandard video signals, such as a VCR in trick mode, to synchronize downstream video circuitry.
