The N bit always indicates the same state as the DC bit set in negative value mode by the CS[2:0]
bits. See the negative value mode part above. The Z bit always indicates the same state as the DC
bit set in zero value mode by the CS[2:0] bits. See the zero value mode part above. The V bit
always indicates the same state as the DC bit set in overflow mode by the CS[2:0] bits. See the
overflow mode part above. The GT bit always indicates the same state as the DC bit set in signed
greater than mode by the CS[2:0] bits. See the signed greater than mode part above.
Note: The DC bit is always updated as the carry/borrow flag for ‘PADDC’ and ‘PSUBC’

3.5.5
Figure 3.14 shows the ALU integer arithmetic operation flow. Table 3.23 shows the variation of
this type of operation. The correspondence between each operand and registers is the same as
ALU fixed-point operations as shown in table 3.22.
The S bit in SR is effective for any ALU fixed-point arithmetic operations in the DSP unit. See
section 3.5.11, Overflow Protection, for details.
