Section 2 Instruction Descriptions
MAC (Multiply and ACcumulate)
Operand Format and Number of States Required for Execution
Notes
1. Flags (N, Z, V) indicating the result of the MAC instruction can be set in the condition-code
2. If ERn and ERm are the same register, the execution addresses are ERn and ERn + 2. After
3. If MACS is modified during execution of a MAC instruction, the result cannot be guaranteed.

execution, the value of ERn is ERn + 4.
It is essential to wait for at least three states after a MAC instruction before modifying MACS.
The multiplier has N-MULT, Z-MULT, and V-MULT flags that indicate the results of MAC
instructions. These flags are separated from the condition-code register (CCR). The values of
these flags can be set in the N, Z, and V flags of the CCR only by the STMAC instruction.
N-MULT and Z-MULT are modified only by MAC instructions. V-MULT retains a value
indicating whether an overflow has occurred in the past, until it is cleared by execution of the
CLRMAC or LDMAC instruction.
The setting and clearing conditions for these flags are given below.
