UART Interface Controller (UART)

6.10

6.10.1 Overview

The NUC505 series provides three channels of Universal Asynchronous Receiver/Transmitters

(UART). The UART Controller performs a serial-to-parallel conversion on data received from the

peripheral and a parallel-to-serial conversion on data transmitted from the CPU. Each UART

Controller channel supports ten types of interrupts. The UART controller also supports IrDA SIR,

RS-485, auto-flow control function and auto-baud rate measuring function.
