Select the output specification for the R13
terminal.
Either complementary output or Pch open drain
output may be selected.
When DC output is selected, R13 becomes a
regular output port. When "BUZZER
INVERTED OUTPUT" is selected, inverted
waveform of the R10 buzzer output is generated
from the R13 terminal. The R13 and R10
control bits become buzzer inverted output when
"1" is written to the R13 and R10 registers,
respectively.
*
The buzzer inverted output may not be
selected when the R10 output type (see
Option 8, "R10 specification") is not set to
buzzer. Moreover, at this point, when the
R10 output type is reselected after selecting
buzzer inverted output, the R10 output type
is fixed at buzzer output.
Buzzer output waveform is shown in Figure
3.3.6.

A FOUT frequency may be selected from
among 8 types, ranging from 256 or 300 Hz
to 32,768 or 38,400 Hz.
FOUT output is normally utilized to provide
clock to other devices but since hazard
occurs at the square wave breaks, great
caution must be observed when using it.
Output waveform is shown in Figure 3.3.5.
