: 16 levels
I/O ports
Input ports: Selectable as input with pull-up resistor/high-impedance input
Output ports: N-channel open drain output (can directly drive LEDs)
Input-output ports: Selectable as input with pull-up resistor/high-impedance input
Selectable as N-channel open drain output/CMOS output
Can be interfaced with external peripherals that use a different power supply than this device
uses. (Power to the output port is supplied from VDDI (separate power suply))
