input/output signal pins. The PIO controller can be programmed to detect an interrupt on a sig-
nal change from each line.
The Watchdog (WD) can be used to prevent system lock-up if the software becomes trapped
in a deadlock.
The Special Function (SF) module integrates the Chip ID, the Reset Status and the Protect
registers.

User Peripherals
Two independently configurable USARTs enable communication at a high baud rate in syn-
chronous or asynchronous mode. The format includes start, stop and parity bits and up to 8
data bits. Each USART also features a Time-out and a Time-guard register, facilitating the
use of the two dedicated Peripheral Data Controller (PDC) channels.
The 3-channel, 16-bit Timer/Counter (TC) is highly programmable and supports capture or
waveform modes. Each TC channel can be programmed to measure or generate different
kinds of waves, and can detect and control two input/output signals. The TC also has three
external clock signals.
