KSZ8041開發(fā)板套件編程器的評(píng)估演示板及套件規(guī)格書PDF中文資料

KSZ8041屬于開發(fā)板套件編程器的評(píng)估演示板及套件。由微芯科技股份有限公司制造生產(chǎn)的KSZ8041評(píng)估和演示板及套件該系列產(chǎn)品提供了一種方便的方法，在經(jīng)過(guò)驗(yàn)證的實(shí)施環(huán)境中評(píng)估某些重點(diǎn)器件的性能或特性。評(píng)估方法通常有完善的文檔說(shuō)明，并且視乎具體情況由評(píng)估軟件提供支持。產(chǎn)品通常由印刷電路板組成，板上已裝有重點(diǎn)器件以及必要或有用的支持元器件，另外也可能包括其他組件，例如電纜或電源。對(duì)于數(shù)量特別多或類別獨(dú)特的器件類別(如 ADC、DAC 和開關(guān)模式電源)，評(píng)估平臺(tái)可組合為一個(gè)單獨(dú)的產(chǎn)品系列。

DESCRIPTION

Some KSZ8041 devices may exhibit receiver errors after the software power down bit (register 0h, bit 11), is set and then cleared. The problem only occurs following software power down. There is no issue following power up or hardware reset.

END USER IMPLICATIONS

When the failure occurs:

? The RXER pin is asserted randomly

? The RXER counter (register 15h) increments

? The RXER interrupt bit (register 1Bh, bit 6) is set

? 100BASE-TX receive side exhibits errors (transmit side functions properly)

? 10BASE-T transmit and receive function properly

The only ways to exit the failure condition are:

? Cycle power off and on

? Set and clear the software power down bit (this method may resolve the issue, but is not guaranteed)
