Associated Documentation
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.
Two USARTs, independently configurable, 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 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 different kinds
of waves, and can detect and control two input/output signals. The TC has also three external
clock signals.
