Assembly Syntax
Preliminary
Add Accumulators
f = f + WREG
WREG = f + WREG
Wd = lit10 + Wd
Wd = Wb + Ws
Wd = Wb + lit5
16-bit Signed Add to Accumulator
f = f + WREG + (C)
WREG = f + WREG + (C)
Wd = lit10 + Wd + (C)
Wd = Wb + Ws + (C)
Wd = Wb + lit5 + (C)
f = f .AND. WREG
WREG = f .AND. WREG
Wd = lit10 .AND. Wd
Wd = Wb .AND. Ws
Wd = Wb .AND. lit5
f = Arithmetic Right Shift f
WREG = Arithmetic Right Shift f
Wd = Arithmetic Right Shift Ws
Wnd = Arithmetic Right Shift Wb by Wns
Wnd = Arithmetic Right Shift Wb by lit5
Bit Clear f
Bit Clear Ws
