Function
Threshold voltage ariable 4-bit analogy input port.
External event pulse input for the timer/event counter or edge
detect vector interrupt input. 1-bit input enable.
Timer/event counter output.
Serial clock input/output.
Serial data output.
Serial data input.
Edge detect vector interrupt input (for detecting both rising and
falling edges).
Edge detect vector interrupt input (detected edge selectable).
Edge detect testable input (for rising edge detection).
Clock output.
Crystal/ceramic connect pin (system clock oscillation).
In case with the external clock, input a signal to X1 and the
antiphase to X2.
System reset input (low level active).
No Connection
Positive power supply.
GND potential.
