CMPL
Operation
RS.L – IMM8
Subtracts the 8 bit constant IMM8 contained in the instruction code from the low byte of the source register
RS.L using binary subtraction and updates the condition code register accordingly.
Remark: There is no equivalent operation using triadic addressing. Comparing the values of two registers
can be performed by using the subtract instruction with R0 as destination register.
