• Stack level

Call stack level

Register stack level

: 16 levels

: 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))
