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 Pro-

User Peripherals
Two USARTs, independently configurable, enable communication at a high baud rate in
Synchronous or Asynchronous Mode. The format includes start, stop and parity bits and
up to 8 data bits. Each USART also features a Timeout and a Time Guard register, facil-
itating 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 dif-
ferent kinds of waves, and can detect and control two input/output signals. The TC also
has 3 external clock signals.
