Notes:
1. CLMP[1:0] controls the clamp algorithm in silicon revision G only. For silicon revisions A through F these two bits
provide the lsbs of the sync level selection.

Description
Line store 1 bypass.
Bypasses linestore 1 when HIGH.
Line store 1 input.
Selects the input of linestore 1:

LS2DLY
Line store 2 delay.
LSTORE2 uses STS to store 1H when LOW and uses
VL to store SAV to EAV (or max count) when HIGH.
Line store 2 delay.
Splits data through LSTORE2, 9 bits chroma and 7 bits
luma when HIGH (chroma combs) and 8 bits chroma and 8 bits luma when
LOW (luma comb).
Bandsplit filter bypass.
Bandsplit filter is bypassed when HIGH.
Bandsplit filter select.

Inverts msb of bandsplit filter.
When HIGH, inverts the msb of the input to

Delays input to GRS decode.
When HIGH, delays the input to the GRS
extraction circuit by 1H.
