Description: Does signed multiplication of 16-bit operands obtained using the contents of general
registers Rm and Rn as addresses. The 32-bit result is added to contents of the MAC register, and
the final result is stored in the MAC register. Rm and Rn data are incremented by 2 after the
operation.
When the S bit is cleared to 0, the operation is 16
the 64-bit result is stored in the coupled MACH and MACL registers.
When the S bit is set to 1, the operation is 16
addition to the MAC register is a saturation operation. For the saturation operation, only the
MACL register is enabled and the result is limited to a range of H'80000000 (minimum) and
H'7FFFFFFF (maximum).
If an overflow occurs, the LSB of the MACH register is set to 1. The result is stored in the MACL
register. The result is limited to a value between H'80000000 (minimum) for overflows in the
negative direction and H'7FFFFFFF (maximum) for overflows in the positive direction.
Note: When the S bit is 0, the SH-2 and SH-DSP CPU perform a 16
