Operation
16-Bits add without Carry
YA ← ( YA ) ( dp +1 ) ( dp )
Compare YA contents with memory pair contents :
(YA) − (dp+1)(dp)
Decrement memory pair
( dp+1)( dp) ← ( dp+1) ( dp) - 1
Increment memory pair
( dp+1) ( dp) ← ( dp+1) ( dp ) + 1
Load YA
YA ← ( dp +1 ) ( dp )
Store YA
( dp +1 ) ( dp ) ← YA
16-Bits subtract without carry
YA ← ( YA ) - ( dp +1) ( dp)

Operation
Bit AND C-flag : C ← ( C ) ∧ ( M .bit )
Bit AND C-flag and NOT : C ← ( C ) ∧ ~( M .bit )
Bit test A with memory :
Z ← ( A ) ∧ ( M ) , N ← ( M₇ ) , V ← ( M₆ )
Clear bit : ( M.bit ) ← “0”
Clear A bit : ( A.bit ) ← “0”
Clear C-flag : C ← “0”
Clear G-flag : G ← “0”
Clear V-flag : V ← “0”
Bit exclusive-OR C-flag : C ← ( C ) ⊕ ( M .bit )
Bit exclusive-OR C-flag and NOT : C ← ( C ) ⊕ ~(M
.bit)
Load C-flag : C ← ( M .bit )
Load C-flag with NOT : C ← ~( M .bit )
Bit complement : ( M .bit ) ← ~( M .bit )
