Test for Zero or Minus
• Bit[4] – S: Sign Bit, S = N V
The S-bit is always an exclusive or between the negative flag N and the two’s comple-
ment overflow flag V. See Table 22 for detailed information.
• Bit[3] – V: Two’s Complement Overflow Flag
The two’s complement overflow flag V supports two’s complement arithmetics. See
Table 22 below for detailed information.
• Bit[2] – N: Negative Flag
The negative flag N indicates a negative result after the different arithmetic and logic
operations. See Table 22 below for detailed information.
• Bit[1] – Z: Zero Flag
The zero flag Z indicates a zero result after the different arithmetic and logic operations.
See Table 22 below for detailed information.
• Bit[0] – C: Carry Flag
The carry flag C indicates a carry in an arithmetic or logic operation. See Table 22 for
detailed information.
