In 10 Hz intermittent output with 1 Hz intervals (mode D), setting the buzzer enable bit to 1 sets
repetition of output for 50 ms then pause for 50 ms over a 500 ms period. Then, after a silent period of 500
ms the output/pause is repeated, and so on. Setting the bit to 0 terminates the buzzer output.
In modes B, C, and D, when the buzzer enable bit is set to 0 during buzzer output, the buzzer completes
output of 50 ms before terminating. The contents of the timer port can be used to determine the buzzer
output state. When the timer port 10 Hz bit is set to 0, the buzzer is output; when the bit is 1, the buzzer is
paused.
Buzzer control is accessed using the OUT1 instruction with the [CN
=
9N, AH] operand on I/O map page

Note: When outputting the buzzer, set P4-0 to output state (set the I/O control port to 1).
