3-11. BUZZER CIRCUIT

The buzzer circuit uses as its input signal P74 from the CPU. This normally Low signal and goes
High on 2 conditions. First on an error tone, P74 goes Clocked until the error condition is cleared.
For a key beep tone, P74 goes High and then returns to its Low state. This pulse is of extremely
short duration.
