Description
Test Register.
Program LOW.
EH/SL Offset Control Bit.
When LOW, the true value of EH and SL is offset by 256.
When HIGH, the true value of EH and SL is offset by 512.
Half Line Enable.
When LOW, half-line blanking occurs on line 283 (NTSC) or line 23 (PAL).
When HIGH, line 283 (NTSC) or line 23 (PAL) is treated as a full line of
active video.
VBI Active Video Enable, Field 2.
The value of VBIENF2 determines which line blanking stops and active line
for ODD fields in NTSC starting from line 4 to line 35 or an EVEN fields for
PAL starting from line 1 to line 32.

PEDHGT1
Description
Composite Pedestal Height.
PEDHGT1 is a 2’s comp value producing a pedestal height from -22.1 IRE
to 21.7 IRE with .345 IRE steps on the composite data path. The default 7.5
IRE pedestal for NTSC-M results from a hex code of 0010110b.
