EtherCAT Slave Controller SoC

USCI - Universal Serial Control Interface Controller (USCI)

2.24.1 Overview

The Universal Serial Control Interface (USCI) is a flexible interface module covering several serial

communication protocols. The user can configure this controller as UART, SPI, or I2C functional protocol.

2.24.2 Features

The controller can be individually configured to match the application needs. The following protocols are

supported:

⚫

UART

⚫

SPI

⚫

I2C

USCI – UART Mode

2.25.1 Overview

The asynchronous serial channel UART covers the reception and the transmission of asynchronous data frames.

It performs a serial-to-parallel conversion on data received from the peripheral, and a parallel-to-serial

conversion on data transmitted from the controller. The receiver and transmitter being independent, frames can

start at different points in time for transmission and reception.

The UART controller also provides auto flow control. There are two conditions to wake-up the system.

2.25.2 Features

⚫

Supports one transmit buffer and two receive buffer for data payload

⚫

Supports hardware auto flow control function

⚫

Supports programmable baud-rate generator

⚫

Support 9-bit Data Transfer (Support 9-bit RS-485)

⚫

Baud rate detection possible by built-in capture event of baud rate generator

⚫

Supports PDMA capability

⚫

Supports Wake-up function (Data and nCTS Wakeup Only)
