Field Bits Type Description
CLP 0rwFCLP Line Polarity
0
B
FCLP and FCL signal polarity is identical.
FCLN signal has inverted FCL signal polarity.
1
B
FCLP signal has inverted FCL signal polarity.
FCLN and FCL signal polarities are identical.
SLP 1rwSOP Line Polarity
0
B
SOP and SO signal polarity is identical.
SON signal has inverted SO signal polarity.
1
B
SOP signal has inverted SO signal polarity.
SON and SO signal polarities are identical.
CSLP 2rwChip Selection Lines Polarity
0
B
EN[3:0] and ENL, ENH, ENC signal polarities
are identical (high active).
1
B
EN[3:0] signal polarities are inverted (low
active) to the ENL, ENH, ENC signal polarities.
Bit CSLP is buffered during a frame transmission.
This means that any change of CSLP becomes valid
first with the start of the next frame transmission.
ILP 3rwSDI Line Polarity
0
B
SDI and SI signal polarities are identical.
1
B
SDI and SI signal polarities are inverted.
