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)
