Section 4 Instruction Features
The overflow prevention function is valid for DSP unit multiplication. Specify it by setting the S
bit of the SR register is set to 1. When an overflow or underflow occurs, the operation result value
is the maximum or minimum value respectively. In DSP unit fixed decimal point multiplication,
overflows only occur for H'8000
result is H'80000000, which means –1.0 rather than the correct answer of +1.0. When the S bit is
1, the overflow prevention function is engaged and the result is H'007FFFFFFF.
4.11
The amount of shift in shift operations is specified either through a register or using a direct
immediate value. Other source operands and destination operands are registers. There are two
types of shift operations: arithmetic and logical. Table 4.21 shows the operation types. The
correspondence between operands and registers is the same as for ALU fixed decimal point
operations, except for immediate operands. The correspondence is shown in table 4.22.
