CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (Output Ports)
When output port R10 is set for FOUT output, it outputs the
clock of fosc3 and fosc1 or the divided fosc1. The clock
frequency is selectable by mask option from the frequencies
listed in Table 4.4.2.

fosc1 / 4

A hazard may occur when the FOUT signal is turned on or off.
R12 can select the following two functions using the mask
option as special output.
(1) Inverse output (MO) of melody output (MO)
Using the MO and MO terminals together, piezoelectric
buzzer may be driven directly. This means the minimum
number of external parts is necessary to play melodies.
(2) Envelope function
An envelope can be added when playing a melody by
connecting the play sound pressure damping capacitor to
terminal R12.
For details, see Chapter 5, "BASIC EXTERNAL WIRING
DIAGRAM", and Section 4.11, "Melody Generator".
