OPERATION
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 ←"OFFH"
Table call :
M(SP) ← (PCH), SP ← SP -1,
M(SP) ← (PCL), SP ← SP -1
PCL ← (Table vector L), PCH ← (Table vector H)

OPERATION
Software interrupt:
B ← “1”, M(SP) ← (PCH), SP ← SP - 1,
M(s) ← (PCL), SP ← S - 1, M(SP) ← PSW,
SP ← SP - 1, PCL ← (0FFDEH), PCH ← (0FFDFH)
Disable interrupts : I ← “0”
Enable interrupts : I ← “1”
No operation
Pop from stack
SP ← SP + 1, Reg. ← M(SP)
Push to stack
M(SP) ← Reg. SP ← SP - 1
Return from subroutine :
SP ← SP+1, PCL ← M(SP), SP ← SP+1, PCH ← M(SP)
Return from interrupt :
SP ← SP+1, PSW ← M(SP), SP ← SP+1,PCL ← M(SP),
SP ← SP+1, PCH ← M(SP)
