CMP.B <EAs>, Rd
Operand Size
Byte
Description
This instruction subtracts the source operand from the contents of an 8-bit register Rd (destination
operand) and sets or clears the condition code bits according to the result. The contents of the 8-bit
register Rd remain unchanged.
Available Registers
Rd: R0L to R7L, R0H to R7H
Rs: R0L to R7L, R0H to R7H
