Hi Group,

I am using the picmaster emulator and emulating the 16C73A.

While letting my application run, I some times will get a brownout reset,
this is apparent because the brownout reset pin in pcon,0 is cleared.
Additionally, the brown out reset always occurs in the same code segment
location.

I have noted that the emulator will let me modify page bit in the PCLATH and
bank bits RP0 after a brown-out reset.  But I can not manually modify the RAM
data using the modify window.

I can single step and any code like BCF MyReg,0 or BSF MyReg,0 will not
affect this flag.

I reviewed some of the information in the MPLAB CD but could not find
anything that told me what happens after a brown out reset.  Is this the
typical response of the chip, that is not to allow changes to RAM.  Do I need
to set the brownout flag PCON,0 before I can restore control of my
application?

Thanks!

Paul
