UART Interface Controller (UART)

6.16.1

Overview

The chip provides six channels of Universal Asynchronous Receiver/Transmitters (UART). The UART

controller performs Normal Speed UART and supports flow control function. 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, LIN and RS-485 function modes and auto-

baud rate measuring function.
