•

The destination operand (dst) contents are incremented by only one.

•

If the increment result is 0, the Z flag is set (1).  In all other cases, the Z flag is cleared (0).

•

If the increment generates a carry for bit 4 out of bit 3, the AC flag is set (1).  In all other cases, the AC flag

is cleared (0).

•

Because this instruction is frequently used for increment of a counter for repeated operations and an indexed

addressing offset register, the CY flag contents are not changed (to hold the CY flag contents in multiple-

byte operation).

INC B;  The B register is incremented.
