Address Name Description
DFF10E CLXCON2 Extended Collision Control


This reg controls when bit planes 7 and 8 are included in collision
detection, and there required state if included. Contents of this
register are reset by a write to CLXCON.


Bit Function Description
15-08 Unused
07 ENBP8 Enable bit plane 8 (match reqd. for collision)
06 ENBP7 Enable bit plane 7 (match reqd. for collision)
05-02 Unused
01 MVBP8 Match value for bit plane 8 collision
00 MVBP7 Match value for bit plane 7 collision

Disable bit planes cannot prevent collisions. Therefore if all
bitplanes are disabled, collision will be continuous, regardless
of the match values.
