SUB
Subtraction
Format:
SUB regi,regj
Operation:
regi <- regi-regj
Description:
The contentsof the RegisterFile j-th registerspecified as sourceis subtractedfrom the
destinationi-th register, leavingthe result in the destinationregister.
Flags:
Z set if result is zero,cleared otherwise.
S setif underflow,cleared otherwise.
Bytes:
2
Cycles:
7
Example:
If the register 4 containsthe value 45 and the register11 containsthe value15, then the
instruction
SUB 4,11
causes the register4 of the Register File to be loaded with the value 30.
10010010 0100|1011
If the register 4 containsthe value 100 and the register11 containsthe value 200,the in-
struction causesthe register4 to be loaded with the value 156 (result+256) and the S
flag to be set.
