1, 2, 3, 4, 1, 2, 3, 4, GPIO Port 0 capable of sinking up to 50 mA/pin, or 21, 22, 23, 24 22, 23, 24, 25 sinking controlled low or high programmable current.Can also source 2 mA current, provide a resistive pull-up, or serve as a high-impedance input.P0.0 and P0.1 provide inputs to Capture Timers A and B, respectively.5, 6, 7, 8, 5, 6, 7, 8, IO Port 1 capable of
Features
- enCoRe⢠USB - enhanced Component Reduction.
- Internal oscillator eliminates the need for anexternal crystal or resonator.
- Interface can auto-configure to operate as PS/2 or USB without the need for external components to switch between modes (no General Purpose I/O [GPIO] pins needed to manage dual mode capability).
- Internal 3.3V regulator for USB pull-up resistor.
- Configurable GPIO for real-world interface without external components.
- Flexib.
