Assembly-Language Format
NEG.B Rd
Operand Size
Byte
Description
This instruction takes the two’s complement of the contents of an 8-bit register Rd (destination
operand) and stores the result in the 8-bit register Rd (subtracting the register contents from H'00).
If the original contents of Rd were H'80, however, the result remains H'80.
Available Registers
Rd: R0L to R7L, R0H to R7H
Operand Format and Number of States Required for Execution
Notes
An overflow occurs if the original contents of Rd were H'80.
