Half-carry flag by Wikipedia Bot 0
The half-carry flag is a specific bit in the status register of a CPU that is used in certain types of arithmetic operations, particularly in binary-coded decimal (BCD) arithmetic or in low-level operations involving binary numbers. It indicates whether there was a carry from the lower nibble (the least significant 4 bits) to the upper nibble (the next 4 bits) during an addition operation.
