BZ, BZ (R10, R13)
BZ and BZ are the buzzer signal output for driving the piezoelectric buzzer. The buzzer signal is
generated by demultiplicaion of fOSC1. The buzzer signal frequency can be selected by software. Also,
a digital envelope can be added to the buzzer signal. See Section 4.11, "Sound Generator", for details.
Notes: When the BZ and BZ output signals are turned ON or OFF, a hazard can result.
When DC output is set for the output port R10, the output port R13 cannot be set for BZ output.
Figure 4.5.2.2 shows the output waveform for BZ and BZ.

SIOF (R11)
When the output port R11 is set for SIOF output, it outputs the signal indicating the running status
(RUN/STOP) of the serial interface. See Section 4.7, "Serial Interface", for details.
FOUT (R12)
When the output port R12 is set for FOUT output, it outputs the clock of fOSC1 or the demultiplied
fOSC1. The clock frequency is selectable with the mask options, from the frequencies listed in Table
4.5.2.2.
