Function
These bits are always read as 0. The write value
should always be 0.
Specifies the operation result status to be set in the T
bit in the SR register if the TC bit is 1. If the S bit of
the SR register is set to 1, an overflow is detected.
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)
TC Bit
0: The T bit of the SR register is not affected by the
1: The T bit of the SR register changes according to
Signed Greater Bit
Indicates that the operation result is positive (except
0), or that operand 1 is greater than operand 2
1: Operation result is positive, or operand 1 is greater
Zero Bit
Indicates that the operation result is zero (0), or that
operand 1 is equal to operand 2
1: Operation result is zero (0), or operands are equal
