DSR Register Bits
Name (Abbreviation)
Reserved bits
Signed greater than bit
(GT)
Zero bit (Z)
Negative bit (N)
Overflow bit (V)
Status selection bits (CS) Designate the mode for selecting the operation result
DSP status bit (DC)
Function
0: Always read out; always use 0 as a write value
Indicates that the operation result is positive
(excepting 0), or that operand 1 is greater than
operand 2
1: Operation result is positive, or operand 1 is greater
Indicates that the operation result is zero (0), or that
operand 1 is equal to operand 2
1: Operation result is zero (0), or equivalence
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
Indicates that the operation result has overflowed
1: Operation result has overflowed
status set in the DC bit
Do not set either 110 or 111
000: Carry/borrow mode
001: Negative value mode
010: Zero mode
011: Overflow mode
100: Signed greater mode
101: Signed above mode
Sets the status of the operation result in the mode
designated by the CS bits
0: Designated mode status not realized (unrealized)
1: Designated mode status realized
smaller
