When I try to do a full chip simulation of an 'RS08 using CW5.1, the simulator reports
that memory locations $221 (PTAPUD) and $222 (PTASE) -- as seen through the paging window -- are not implemented. (Location $220 (PTAPE) _is_, however.)
Certainly, the _simulator_ doesn't care about and of these three locations. I _do_ though, since my code needs to initialize these locations if I want pull ups and the alleged slew rate protections.
So my question is: is this just a problem on my CW installation, or is it part of some clever plan by the simulator makers?
Has anyone else experienced this problem?
Thanks in advance,
