Abstract: This document explains how the Cupertino (MAXREFDES5#) subsystem reference design meets the higher resolution, higher voltage,and isolation needs of industrial control and industrial automation applications. Hardware and firmware design files as well as FFTs andhistograms from lab measurements are provided.

The MAX9257/MAX9258 programmable serializer/deserializer (SerDes) devices transfer both video data and control signals over the same twisted-pair cable. However, control data can only be transmitted during the vertical blank time, which is indicated by the control-channel-enabled output (CCEN) signal. The electronic control unit (ECU) firmware designer needs to know how quickly to respond to the CCEN signal before it times out and how to calculate this duration. This application note describes how to calculate the duration of the CCEN for the MAX9257/MAX9258 SerDes chipset. The calculation is based on STO timeout, clock frequency, and UART bit timing. The CCEN duration is programmable and can be closed if not in use.

單片機(jī)作為一種微型計(jì)算機(jī)，其內(nèi)部具有一定的存儲單元（8031除外），但由于其內(nèi)部存儲單元及端口有限，很多情況下難以滿足實(shí)際需求。為此介紹一種新的擴(kuò)展方法，將數(shù)據(jù)線與地址線合并使用，通過軟件控制的方法實(shí)現(xiàn)數(shù)據(jù)線與地址線功能的分時(shí)轉(zhuǎn)換，數(shù)據(jù)線不僅用于傳送數(shù)據(jù)信號，還可作為地址線、控制線，用于傳送地址信號和控制信號，從而實(shí)現(xiàn)單片機(jī)與存儲器件的有效連接。以單片機(jī)片外256KB數(shù)據(jù)存儲空間的擴(kuò)展為例，通過該擴(kuò)展方法，僅用10個(gè)I/O端口便可實(shí)現(xiàn)，與傳統(tǒng)的擴(kuò)展方法相比，可節(jié)約8個(gè)I/O端口。 Abstract: As a micro-computer,the SCM internal memory has a certain units(except8031),but because of its internal storage units and the ports are limited,in many cases it can not meet the actual demand.So we introduced a new extension method,the data line and address lines combined through software-controlled approach to realize the time-conversion functions of data lines and address lines,so the data lines not only transmited data signals,but also served as address lines and control lines to transmit address signals and control signals,in order to achieve an effective connection of microcontroller and memory chips.Take microcontroller chip with256KB of data storage space expansion as example,through this extension method,with only10I/O ports it was achieved,compared with the traditional extension methods,this method saves8I/O ports.
