Function
Variable threshold voltage 4-bit analog input port.
External event pulse input to timer/event counter.
Or edge detection vectored interrupt input, or 1-bit input
is also possible.
Timer/event counter output.
Serial clock input/output.
Serial data output.
Serial data input.
Edge detection vector interrupt input (detection of both
rising and falling edges)
Edge detection vector interrupt input (detection edge
selectable)
Edge detection test input (rising edge detection)
Clock output
System clock oscillation crystal/ceramic connection pin.
When an external clock is used, the clock is input to X1
and the inverted clock is input to X2.
System reset input (low-level active).
Internally Connected. IC pin should be connected to V
DD
directly.
Positive power supply.
GND potential.
