Responding to: ???'s previous message
Im stuck on that bit of code still.
I type

Save This Code
 MOV ACC.MUX_BIT_NO, BIT_1
 MOV ACC,MUX_BIT_NO+1, BIT_2

 


But I'm getting error A18

BIT_1 and BIT_2 are BITs and MUX_BIT_NO is a BYTE


On MCS51 You can MOVe bits only to or from Carryflag:
mov Yourbit,C
mov C,Yourbit

If Your aim is to copy BIT_1 and BIT_2 into variable positions in ACCumulator,
Your way is too HLL-ish.

.............
mov r2,#0
mov r3,#0
jnb BIT_1,skipmybit1
mov a,MUX_BIT_NO
call routine_number_tobit
mov r2,a
skipmybit1:
jnb BIT_2,skipmybit2
mov a,MUX_BIT_NO
inc a ;????or mov a,MUX_BIT_NO+1
call routine_number_tobit
mov r3,a

skipmybit2
clr a
orl a,r2
orl a,r3
..........



routine_number_tobit
