Invalid Register

mov r0,(register number + selected bank /8)) works.

e.g. in bank zero

RB0R5 = 5
RB1R5 = 5+8
RB2R5 = 5+16
RB3R5 = 5+24

mov r0,RB0R5 ;will work

mov r0,(register number + selected bank /8)) works.

e.g. in bank zero

RB0R5 = 5
RB1R5 = 5+8
RB2R5 = 5+16
RB3R5 = 5+24

mov r0,RB0R5 ;will work

So will MOV R0,AR0. AR0 is calculated using the current register bank.

Keil feature I did not know of.

Erik,

Don't mention that you found out over here or who you it heard from in any 8052.com posts lest you upset the natives ;-)

Keil feature? Isn't this just plain old 8051 assembler?
