[Sdcc-user] Attempt to write to invalid file register

[Peter C. <pe...@pe...>]

Chaps,

I'm getting the following error from gpsim and the code does not work on a=
=20
PIC.  My suspicion is that my variables have run out of file registers or=20
are attempting to overright ones they should not.  I'm attemping to write=20
code for the PIC 16F877.

Any hints?

=46rom GPSIM, as it stops:

attempt write to invalid file register
    address 0x90,   value 0xff
0x0000000004C61337  0x08EB 0x0090 movwf _T1CON_bits
