Greetings,
I am using MPLAB 6.10.0.0 on an 18F458.
My program is trying to read CONFIG registers
for information on the OSC selection.

When I attempt to read 0x300000 and 0x300001 from
MPLAB SIM I always get a return value of zero, regardless
of how CONGIG1L and CONFIG1H are set. If I set TBLPTR to
normal program space it seems to work fine.

According to the datasheet, the config areas can be
accessed using table reads and table writes. I am
using TBLRD in this case.

Has anyone else tried this? May I assume it's a
shortcoming of MPLAB SIM and not some other error?

Thanks for any responses,
Lyle Hazelwood
