■ Additional features only provided on SIO pins:

❐ Higher drive strength than GPIO

❐ Hot swap capability (5 V tolerance at any operating VDD)

❐ Programmable and regulated high input and output drive

levels down to 1.2 V

❐ No analog input, CapSense, or LCD capability

❐ Over voltage tolerance up to 5.5 V

❐ SIO can act as a general purpose analog comparator

■ USBIO features:

❐ Full speed USB 2.0 compliant I/O

❐ Highest drive strength for general purpose use

❐ Input, output, or both for CPU and DMA

❐ Input, output, or both for digital peripherals

❐ Digital output (CMOS) drive mode

❐ Each pin can be an interrupt source configured as rising

edge, falling edge, or both edges
