3.4.2 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. Do
not use these read-modify-write instructions on write-only locations.
Refer to the following list of instructions.
