Data Shift Instructions
Section 3-9
Description
SRD(075) shifts data between St and E by one digit (4 bits) to the right. “0” is
placed in the leftmost digit (bits 15 to 12 of E), and the content of the rightmost
digit (bits 3 to 0 of St) is lost.
Flags
Precautions
When St is greater than E, an error will be generated and the Error Flag will
turn ON.
When SRD(075) is executed, the Equals Flag and Negative Flag will turn
OFF.
Note When large amounts of data are shifted, the instruction execution time is quite
long. Always take care that the power is not cut while SRD(075) is being exe-
cuted, causing the shift operation to stop halfway through.
