Section 3 DSP Operating Unit
3.5.11
The S bit in SR is effective for any arithmetic operations executed in the DSP unit, including the
SH’s standard multiply and MAC operations. The S bit in SR is used as the overflow protection
enable bit. The arithmetic operation overflows when the operation result exceeds the range of
two’s complement representation without guard-bit parts. Table 3.31 shows the definition of
overflow protection for fixed-point arithmetic operations, including fixed-point signed by signed
multiplication described in section 3.5.7, Fixed-Point Multiply Operation. Table 3.32 shows the
definition of overflow protection for integer arithmetic operations. The lower word of the
saturation value of the integer arithmetic operation is don’t care. Lower word value cannot be
guaranteed.
When the overflow protection is effective, overflow never occurs. So, the V bit is cleared, and the
DC bit is also cleared when the overflow mode is selected by the CS[2:0] bits.
