The AT91FR4042 provides two identical, full-duplex, universal synchronous/asynchro-
nous 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 AT91FR4042 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 mea-
surement, 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.
