Supports both low-speed (1.5 Mbps) and full-speed (12Mbps) USB devices.
Built-in DMA for real-time data transfer
One UART (serial I/O) blocks with interrupt-based operation
Full set of MODEM control functions (CTS, RTS, DSR, DTR, RI and DCD)
Fully programmable serial-interface characteristics:
Break generation and detection
False start bit detection
Parity, overrun, and framing error detection
Full prioritized interrupt system controls
Two programmable 24-bit timers with 8-bit pre-scalar
One programmable 24-bit Watch-Dog timer
One-short mode, period mode or toggle mode operation
21 programmable I/O ports
I/O ports Configurable for Multiple functions
18 interrupt sources, including 4 external interrupt sources
Programmable normal or fast interrupt mode (IRQ, FIQ)
Programmable as either edge-triggered or level-sensitive for 4 external interrupt sources
Programmable as either low-active or high-active for 4 external interrupt sources
Priority methodology is encoded to allow for interrupt daisy-chaining
Automatically mask out the lower priority interrupt during interrupt nesting
Programmable as an input or output pin
