Description
Embedded Characteristics
The Universal Asynchronous Receiver Transmitter features a two-pin UART that can be used for
communication and trace purposes and offers an ideal medium for in-situ programming solu-
tions. Moreover, the association with two peripheral DMA controller (PDC) channels permits
packet handling for these tasks with processor time reduced to a minimum.
• Two-pin UART
– Implemented Features are USART Compatible
– Independent Receiver and Transmitter with a Common Programmable Baud Rate
– Even, Odd, Mark or Space Parity Generation
– Parity, Framing and Overrun Error Detection
– Automatic Echo, Local Loopback and Remote Loopback Channel Modes
– Interrupt Generation
– Support for Two PDC Channels with Connection to Receiver and Transmitter
