CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (Output Ports)
FOUT (R00)
When output port R00 is set for FOUT output, this port will
generate fosc (CPU operating clock frequency) or clock
frequency divided into fosc. Clock frequency may be se-
lected individually for F1–F4, from among 5 types by mask
option; one among F1–F4 is selected by software and used.
The types of frequency which may be selected are shown in
Table 4.4.2.
Output ports R01 and R00 may be set to BUZZER output
and BUZZER output (BUZZER reverse output), respectively,
allowing for direct driving of the piezo-electric buzzer.
BUZZER output (R00) may only be set if R01 is set to
BUZZER output. In such case, whether ON/OFF of the
BUZZER output is done through R00 register or is control-
led through R01 simultaneously with BUZZER output is
also selected by mask option.
The frequency of buzzer output may be selected by software
to be either 2 kHz or 4 kHz.

FOUT clock frequency
A hazard may occur when the FOUT signal is turned on or off.
