Procedure for canceling data protection
Set a frequency of the signal to be output from pin 1.
Examples 64 Hz: (0 0 1 0) (duty cycle: 1/2)
1 Hz: (0 1 0 1) (duty cycle: 1/8192)
Banks are switched. The stop bit is cleared.
The reset bit is cleared
Preparation for a carry (oscillation).
When an alarm occurs, a carry is inhibited.
