STMAC (STore from MAC register)
Operation
MACH
or
MACL
Assembly-Language Format
STMAC MAC register, ERd
Operand Size
Longword
Description
This instruction moves the contents of a multiply-accumulate register (MACH or MACL) to a
general register. If the transfer is from MACH, the upper 22 bits transferred to the general register
are a sign extension.
This instruction is supported by the H8S/2600 CPU only.
Available Registers
ERd: ER0 to ER7

Condition Code
H: Previous value remains unchanged.
N: Set to 1 if a MAC instruction resulted in a
Z: Set to 1 if a MAC instruction resulted in a
V: Set to 1 if a MAC instruction resulted in
C: Previous value remains unchanged.
Note: * Execution of this instruction copies the N, Z,
negative MAC register value; otherwise
cleared to 0.
zero MAC register value; otherwise
cleared to 0.
an overflow; otherwise cleared to 0.

and V flag values from the multiplier to the
condition-code register (CCR). If the STMAC
instruction is executed after a CLRMAC or
LDMAC instruction with no intervening MAC
instruction, the V flag will be 0 and the N and Z
flags will have undetermined values.
