Hello,

I have been programming this PIC for several years without a problem, until 
now, that we got a new batch of PIC18F2610s date coded 0804.

Same program, same configuration, same board, same programmer, etc... Older 
PICs dated 04XX up to 07XX work perfect, only the new ones we got don't 
work.

I have isolated the problem to PortA. For example:

PortA configured as Digital I/O (no analog inputs) ADCON1=B'00111111'
bsf PORTA,3
bsf PORTA,5
after executing this instructions PORTA,3 is LOW (!!!) and PORTA,5 is HIGH

but if I reverse the instructions:
bsf PORTA,5
bsf PORTA,3
both PORTA,3 and PORTA,5 are HIGH

I may have been doing something wrong and never showed up until these new 
PICs or something changed on the silicon, that I have not been able to 
pinpoint in the erratas. So any help will be greatly appreciated.

Gabriel
