Operation
Branch if bit clear :
if ( bit ) = 0 , then pc ← ( pc ) + rel
Branch if bit set :
if ( bit ) = 1 , then pc ← ( pc ) + rel
Branch if carry bit clear
if ( C ) = 0 , then pc ← ( pc ) + rel
Branch if carry bit set
if ( C ) = 1 , then pc ← ( pc ) + rel
Branch if equal
if ( Z ) = 1 , then pc ← ( pc ) + rel
Branch if minus
if ( N ) = 1 , then pc ← ( pc ) + rel
Branch if not equal
if ( Z ) = 0 , then pc ← ( pc ) + rel
Branch if plus
if ( N ) = 0 , then pc ← ( pc ) + rel
Branch always
pc ← ( pc ) + rel
Branch if overflow bit clear
if (V) = 0 , then pc ← ( pc) + rel
Branch if overflow bit set
if (V) = 1 , then pc ← ( pc ) + rel
Subroutine call
M( sp)←( pcH ), sp←sp - 1, M(sp)← (pcL), sp ←sp - 1,
if !abs, pc← abs ; if [dp], pcL← ( dp ), pcH← ( dp+1 ) .
Compare and branch if not equal :
if ( A ) ≠ ( M ) , then pc ← ( pc ) + rel.
Decrement and branch if not equal :
if ( M ) ≠ 0 , then pc ← ( pc ) + rel.
Unconditional jump
pc ← jump address
U-page call
M(sp) ←( pcH ), sp ←sp - 1, M(sp) ← ( pcL ),
sp ← sp - 1, pcL ← ( upage ), pcH ← ”0FFH” .
Table call : (sp) ←( pcH ), sp ← sp - 1,
M(sp) ← ( pcL ),sp ← sp - 1,
pcL ← (Table vector L), pcH ← (Table vector H)
