[comp.sys.amiga.tech] ECS register description

hkr@mcshh.hanse.de (Holger Kruse) (10/16/90)

Does anyone have a detailed description of the new ECS registers,
their usage, bitmapping etc. ?

I just have the names of the new registers (like "bplcon3",
"beamcon0","bplhmod" etc.), not their meaning. (I do not have the
developer package of Kick2.0.)

In the November-issue of "KICKSTART", a German Amiga magazine,
Edwin Bielawski published the following description of "beamcon0"
(translated to English):
Bit 0:  do not invert horizontal synch
Bit 1:  do not invert vertical synch
Bit 2:  do not invert composite synch
Bit 4:  allow variable composite synch signal
Bit 5:  1=PAL-Mode, 0=NTSC-Mode
Bit 7:  allow free programming (caution !)
Bit 8:  allow variable horizontal synch signal
Bit 9:  allow variable vertical synch signal

Unfortunately, I do not have a description of the "free programming mode"
and all the other registers. Can someone help me ?
