Assembly Syntax Description Words Cycles

ASR f {,WREG} Destination = arithmetic right shift f 1 1

ASR Ws,Wd Wd = arithmetic right shift Ws 1 1

ASR Wb,#lit4,Wnd Wnd = arithmetic right shift Wb by lit4 1 1

ASR Wb,Wns,Wnd Wnd = arithmetic right shift Wb by Wns 1 1

LSR f {,WREG} Destination = logical right shift f 1 1

LSR Ws,Wd Wd = logical right shift Ws 1 1

LSR Wb,#lit4,Wnd Wnd = logical right shift Wb by lit4 1 1

LSR Wb,Wns,Wnd Wnd = logical right shift Wb by Wns 1 1

RLC f {,WREG} Destination = rotate left through Carry f 1 1

RLC Ws,Wd Wd = rotate left through Carry Ws 1 1

RLNC f {,WREG} Destination = rotate left (no Carry) f 1 1

RLNC Ws,Wd Wd = rotate left (no Carry) Ws 1 1

RRC f {,WREG} Destination = rotate right through Carry f 1 1

RRC Ws,Wd Wd = rotate right through Carry Ws 1 1

RRNC f {,WREG} Destination = rotate right (no Carry) f 1 1

RRNC Ws,Wd Wd = rotate right (no Carry) Ws 1 1

SL f {,WREG} Destination = left shift f 1 1

SL Ws,Wd Wd = left shift Ws 1 1

SL Wb,#lit4,Wnd Wnd = left shift Wb by lit4 1 1

SL Wb,Wns,Wnd Wnd = left shift Wb by Wns 1 1

Note: When the optional {,WREG} operand is specified, the destination of the instruction is WREG. When

{,WREG} is not specified, the destination of the instruction is the file register f.
