CHAPTER 7 DETAILED EXECUTION INSTRUCTIONS

7.31

BEORH (Eor 4-bit Immediate Data to Higher 4 Bits of Byte
Data in Memory)

Takes the logical exclusive OR of the 4-bit immediate data and the higher 4 bits of byte
data at memory address "Ri", stores the results to the memory address corresponding
to "Ri".
The CPU will not accept hold requests between the memory read operation and the
memory write operation of this request.
