READ-MODIFY-WRITE INSTRUCTIONS
These instructions read a memory location or a register, modify or test its contents, and
write the modified value back to memory or to the register. The test for negative or zero
(TST) instruction is an exception to the read-modify-write sequence since it does not modify
the value. Refer to the following list of instructions.
