Select the output specification for the R01 terminal.
Either complementary output or Pch open drain
output may be selected.
The circuit configuration is the same as that of the
output port R00 (Figure 3.3.2).

Select the output specification and the output type
for the R02 terminal.

Output specification
Either complementary output or Pch open drain
output may be selected.
The circuit configuration is the same as that of the
output port R00 (Figure 3.3.2).
•
Output type
Either DC output or FOUT output may be
selected.
When DC output is selected, R02 becomes a
regular output port.
When the R02 register is set to "1", the R02
terminal output goes high (V
DD
), and goes low
(V
SS
) when set to "0".
The output waveform is shown in Figure 3.3.3.
When FOUT is selected, a clock with a set
frequency can be output from the R02 terminal.
When the FOUT bit (R02 register) is set to "1",
50% duty and V
DD
–V

amplitude square wave is
generated at the specified frequency. When set to
"0", the FOUT terminal goes low (V
SS
). A FOUT
frequency may be selected from among 8 types,
ranging from f
OSC
/256 to f
OSC
/2.
The 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.
The output waveform is shown in Figure 3.3.4.
