User Peripherals
7.2.1
USART: Universal Synchronous/
Asynchronous Receiver Transmitter
The AT91FR40162S provides two identical, full-duplex, universal synchronous/asynchronous
receiver/transmitters.
Each USART has its own baud rate generator, and two dedicated Peripheral Data Controller
channels. The data format includes a start bit, up to 8 data bits, an optional programmable parity
bit and up to 2 stop bits.
The USART also features a Receiver Timeout register, facilitating variable length frame support
when it is working with the PDC, and a Time-guard register, used when interfacing with slow
remote equipment.
7.2.2
TC: Timer Counter
The AT91FR40162S features a Timer Counter block that includes three identical 16-bit timer
counter channels. Each channel can be independently programmed to perform a wide range of
functions including frequency measurement, event counting, interval measurement, pulse gen-
eration, delay timing and pulse width modulation.
The Timer Counter can be used in Capture or Waveform mode, and all three counter channels
can be started simultaneously and chained together.
