I in http://www.8052.com/faqs.phtml?FAQ=123234 said: proprietary protocols, JTAG (uPSD3xxx, VERSA). For a start, it may be worth noting that JTAG itself is not proprietary. JTAG specifies a standard, clocked serial interface - much as SPI specifies a a standard, clocked serial interface. The proprietary part lies in how the standard interface is used for the purpose of programming the chip! Yeah, certainly. These chips even tend to omit the boundary scan, which was the original purpose of JTAG (I don't know about the SiLabs not Ramtron/Goal Versas but for certain the uPSDs don't have the boundary scan implemented in any form). However, my concern is to give the newbies an initial information in the FAQ, for them this knowledge is superfluous, isn't it... JW [edit]I stitched something up, can you please have a look at it... |
