Reset Input. RST is an active-low input, referenced to V
which can be configured to put the device in the power-up reset condition and reset the
PWM and blink timing.
Input/Output Port. P1/INT is configurable as an open-drain I/O or as a transition detection
interrupt output.
Ground
Input/Output Port. P2/OSCIN is configurable as a push-pull I/O, open-drain I/O, or as the
PWM/blink/timing oscillator input.
Input/Output Port. P3/OSCOUT is configurable as a push-pull I/O, open-drain I/O, or as
the PWM/blink/timing oscillator output.
Input/Output Port. P4 is configurable as a push-pull I/O or an open-drain I/O.
