5-16
ADDS
A,#n
Binary Code:
0 1 1 1
d d d d
Description:
The specified 4-bit data n is added to the accumulator and the sum is stored in the
accumulator.
Operation:
(A)
← (A) + #n
Flags:
SF : Set if a carry occurred, cleared otherwise
SL : Unaffected
Example:
CLR
A
; Clear A to zero
ADDS
A,#4H
; Add 4H to A, it leaves 4H in A
SUBS
A,@HL
Binary Code:
0 0 1 1
1 1 0 0
Description:
SUBS subtracts the contents of accumulator from the contents of indirect data memory,
leaving the result in the accumulator.
The contents of source operand are unaffected.
Operation:
(A)
← M [(H,L)] - (A)
Flags:
SF : Set if no borrow occurred, cleared otherwise
SL : Unaffected
Example:
Assume RAM address holds 0CH
MOV
L,#8H
MOV
A,L
SUBS
A,@HL
; Subtract A from 0CH; it will leave 4H in A
INCS
A,@HL
Binary Code:
0 0 1 1
1 1 1 0
Description:
The contents of indirect data memory are incremented by one and the result is loaded into
the accumulator.
The contents of indirect data memory are unaffected.
Operation:
(A)
← M [(H,L)] + 1
Flags:
SF : Set if a carry occurred, cleared otherwise
SL : Unaffected
Example:
Assume RAM address holds 6H
CLR
A
; Clear A to zero
INCS
A,@HL
; Increment 6H by one and leave 7H in A
