 		 #90302 - ASM instructions & USING
Responding to: ???'s previous message
Nick:

Do you have parts of the ISR in assembler? If yes... note that it is not enough to switch banks by modifying PSW. The assembler also needs to know about it, becuase the opcode of a few instructions is different, depending on the register bank.

BEC.
