49.1 Description

The Universal Asynchronous Receiver Transmitter (UART) features a two-pin UART that can be used for communication and trace purposes and offers an ideal medium for in-situ programming solutions.

Moreover, the association with a peripheral DMA controller (PDC) permits packet handling for these tasks with processor time reduced to a minimum.

The UART receiver can be bypassed to get direct access to the analog comparator.

The optical link establishes electrically isolated serial communication with hand-held equipment, such as calibrators compliant with the ANSI-C12.18 or IEC62056-21 standard.
