OPERATION
Clear V-flag : V ← “0”
Compare accumulator contents with memory contents
A - (M)
Compare YA contents with memory pair contents :
YA - (dp+1)(dp)
Compare X contents with memory contents
X - (M)
Compare Y contents with memory contents
Y - (M)
1’s complement : (dp) ← ~(dp)
Decimal adjust for addition
Decimal adjust for substraction
Decrement and branch if not equal :
if (M) ≠ 0, then PC ← PC + rel.
Decrement
M←M-1
Decrement memory pair : (dp+1)(dp) ← {(dp+1)(dp)} - 1
Disable interrupts : I ← “0”
Divide : YA/A ← Q:A, R:Y
Enable interrupts : I ← “1”
Exclusive OR
A ← A ⊕ (M)
Bit exclusive-OR C-flag : C ← C ⊕ (M.bit)
Bit exclusive-OR C-flag and NOT : C ← C ⊕ ∼(M.bit)
Increment
(M) ← (M) + 1
Increment memory pair : (dp+1)(dp) ← {(dp+1)(dp)} + 1
Unconditional jump
PC ← jump address
