Fifth HBLK toggle position for even lines in HBLK Mode 0 and HBLK Mode 1.
Description
Enables different HBLK toggle position operation.
0: normal mode. Six toggle positions available for even and odd lines.
1: pixel mixing mode. In addition to the six toggle positions, the HBLKSTART,
2: advanced HBLK mode. Divides HBLK interval into six repeat areas. Uses
3: test mode only. Do not access.

HBLK Repeat Area 5. Number of H2 repetitions for HBLKSTARTA/B/C.
HBLK Repeat Area Start Position A for HBLK Mode 2. Set to 8191 if not used.
HBLK Repeat Area Start Position B for HBLK Mode 2. Set to 8191 if not used.
HBLK Repeat Area Start Position C for HBLK Mode 2. Set to 8191 if not used.
If even/odd alternation is not needed, set toggles for even/odd the same.
HBLKEND, HBLKLEN, and HBLKREP registers can be used to generate HBLK
patterns. If even/odd alternation is not need, set toggles for even/odd the same.
HBLKSTARTA/B/C and RA*H*REPA/B/C registers.
