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.
