Timer control signal pin
to the timer.
In external clock mode these signals are synchronized
with the internal clock.
Input pin for count operation control signals to the
timer
In MODE0 through MODE3, the input signal is a gate
signal. In MODE4, the pins input an external trigger
signal.
Timer output pin
The output waveform is determined by the mode
setting:
At reset, an “L” level signal is output.
Prescaler asynchronous clock pin
Input can be asynchronous with respect to the system
clock signal input at the CLOCK pin.
If an external clock signal is selected by the PRS0 and
PRS1 registers, this signal can be used as a source
clock for the prescaler. The clock signal divided by the
prescaler is output at the PRSCK0, PRSCK1 pins.
If these pins are not used, they should be fixed at “L”
level.
An “L” level signal is output at reset.
These pins are used to input an external clock signal
• Periodic signal waveform output
• Square wave output
• One-shot pulse waveform output
