AX58200

EtherCAT Slave Controller SoC

UART Interface Controller (UART)

2.16.1 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.
