[Description]
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).
[Description example]
INC B;
The B register is incremented.
