Mnemonic Functions

MPS

Store the current result of the internal EXIO operations

Operand None

Explanation:
To save the content in the accumulative register into the operational result (the pointer of operational
result will plus 1).

Mnemonic Functions

MRD

Read the current result of the internal EXIO operations

Operand None

Explanation:
To read the operational result and store it into the accumulative register (the pointer of operational
result stays intact).

Mnemonic Functions
