Re: sra

Shifts register sX right by one place injecting the value of the carry flag

Added after 4 minutes:

SR0, SR1, SRX, SRA, RR of the shift and rotate group 358 all modify the contents of a single register sX to the right. SL0, SL1, SLX, SLA, RL all modify the contents of a single register sX to the left. These instructions effect the flags.

SR0/SL0—Shifts register sX right/left by one place injecting "0".

SR1/SL1—Shifts register sX right/left by one place injecting "1".

SRX/SLX—Shifts register sX right/left by one place injecting MSB/LSB.

SRA/SLA—Shifts register sX right/left by one place injecting the value of the carry flag.

RR/RL—Rotates register sX right/left by one place injecting LSB/MSB.
