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 )
Bit OR C-flag : C ( C ) ( M .bit )
Bit OR C-flag and NOT : C ( C ) ~( M .bit )
Set bit : ( M.bit ) “1”
Set A bit : ( A.bit ) “1”
Set C-flag : C “1”
Set G-flag : G “1”
Store C-flag : ( M .bit ) C
Test and clear bits with A :
A - ( M ) , ( M ) ( M ) ~( A )
Test and set bits with A :
A-(M), (M)(M)(A)
