Operation
Software interrupt : B ← ”1”, M(sp) ← (pcH), sp ←sp-1,
M(s) ← (pcL), sp ← sp - 1, M(sp) ← (PSW), sp ← sp -1,
pcL ← ( 0FFDEH ) , pcH ← ( 0FFDFH) .
Disable all interrupts : I ← “0”
Enable all interrupt : I ← “1”
No operation
sp ← sp + 1, A ← M( sp )
sp ← sp + 1, X ← M( sp )
sp ← sp + 1, Y ← M( sp )
sp ← sp + 1, PSW ← M( sp )
M( sp ) ← A , sp ← sp - 1
M( sp ) ← X , sp ← sp - 1
M( sp ) ← Y , sp ← sp - 1
M( sp ) ← PSW , 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 )
