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-
tect registers.
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,
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 dif-
ferent kinds of waves, and can detect and control two input/output signals. The TC has
also three external clock signals.
