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.
