03ZSTI2-00-501-RS

处理器25 MHz 32位MC68040或MC68LC040微处理器DRAM 1或4MB共享DRAM，夹层模块上具有奇偶校验保护；或夹层板上具有ECC保护的4、8、16或32MB共享DRAM请注意以下已知问题及其解决方法：当03ZSTI2-00-501-RS系列板上的RESET（重置）按钮按下的时间超过最小时间长度时，奇偶性DRAM刷新可能会被禁止，内存内容可能会丢失。此时间长度可能因板而异，也可能因环境条件而异！警告：如果您打算在重置后检查内存，请在按下重置按钮后尽快释放重置按钮，以确保奇偶性DRAM内容不会被更改。注意：在200/300系列板上，未***为ECCprotected的DRAM受奇偶校验保护。奇偶性DRAM的信息在本指南的MCchip章节中给出，ECC DRAM在MCECC章节中给出。（在以后的版本中，700/800系列奇偶校验在非ECC DRAM上不受支持，03ZSTI2-00-501-RS目前该系列中只有一个板上有奇偶校验。所有700/800序列板上的奇偶校验必须保持禁用状态。）

产品英文详情料:

Processor 25 MHz 32-bit MC68040 or MC68LC040 microprocessor DRAM 1 or 4MB of shared DRAM with parity protection on a mezzanine module; or 4, 8, 16, or 32MB of shared DRAM with ECC protection on a mezzanine board Note the following known problem and its work-around: When the RESET button on an 03ZSTI2-00-501-RSSeries board is depressed for longer than a minimum length of time, Parity DRAM refresh may be inhibited and memory contents may be lost. This timelength may differ from one board to another and may vary with environmental conditionals. ! Caution If you intend to examine memory subsequent to a reset, release the RESET button as quickly as possible after depressing it to ensure that Parity DRAM contents will not be altered.03ZSTI2-00-501-RSNotes On 200/300 Series boards, DRAM not specified as ECCprotected is parity-protected. The Parity DRAM’s information is given in the MCchip chapter of this Guide, the ECC DRAM’s is in the MCECC chapter. (In the later, 700/800 Series parity is unsupported on nonECC DRAM, which currently comes on only one board in that Series. Parity must remain disabled on all 700/800 Series boards.)03ZSTI2-00-501-RS
