Function
Negative Bit
Indicates that the operation result is negative, or that
operand 1 is smaller than operand 2
1: Operation result is negative, or operand 1 is
Overflow Bit
Indicates that the operation result has overflowed
1: Operation result has overflowed
DC Bit Status Selection
Designate the mode for selecting the operation result
status to be set in the DC bit
000: Carry/borrow mode
001: Negative value mode
010: Zero mode
011: Overflow mode
100: Signed greater mode
101: Signed greater than or equal to mode
110: Reserved (setting prohibited)
111: Reserved (setting prohibited)
DSP Status Bit
Sets the status of the operation result in the mode
designated by the CS bits
0: Designated mode status has not occurred (false)
1: Designated mode status has occurred
Indicates the operation result by carry or borrow
regardless of the CS bit status after the PADDC or
PSUBC instruction has been executed.
