BitFlag positionDescriptionZ6Contains results of last arithmetic or compare result (0 for non-zero, 1 for zero).011Indicates that an overflow has occurred in the most significant bit from an arithmetic operation.P2D10

What is the purpose of the Z bit?

When the Z bit is 0 What is the result of 0?

FlagExplanationN = 0The result is 0, which is considered positive, and so the N (negative) bit is set to 0 .Z = 1The result is 0, so the Z (zero) bit is set to 1 .C = 1We lost some data because the result did not fit into 32 bits, so the processor indicates this by setting C (carry) to 1 .
