AT91X40 Series
The AT91X40 Series provides two identical, full-duplex, universal synchronous/asyn-
chronous receiver/transmitters.
Each USART has its own baud rate generator, and two dedicated Peripheral Data Con-
troller 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 interfac-
ing with slow remote equipment.
The AT91X40 Series 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 generation, 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.
