nal clock or external crystal or resonator
❐ Configurable I/O for real world interface without external com-
ponents
■ Enhanced 8-bit Microcontroller

❐ 2 mA source current on all GPIO pins.
❐ Configurable 8 or 50 mA per pin current sink on designated
pins
❐ Each GPIO port supports high impedance inputs, config-
urable pull up, open drain output, CMOS and TTL inputs, and
CMOS output
❐ Maskable interrupts on all I/O pins
■ SPI Serial Communication
❐ Master or slave operation
❐ Configurable up to 2 Mbit per second transfers
