It allows the MCU diagnostic keeping the application in a safe sate."，当LBIST故障时不会释放(即置高)RSTB，那为什么还会使MCU开启诊断,我是一个新手，让您见笑了，还望多多指点!</P> Tue, 13 Jun 2023 05:50:02 GMT https://community.nxp.com/t5/%E7%94%B5%E6%BA%90%E7%AE%A1%E7%90%86%E8%8A%AF%E7%89%87%E4%B8%AD%E6%96%87%E7%A4%BE%E5%8C%BA/FS6523%E8%8A%AF%E7%89%87/m-p/1667942#M98 jiadian666 2023-06-13T05:50:02Z https://community.nxp.com/t5/%E7%94%B5%E6%BA%90%E7%AE%A1%E7%90%86%E8%8A%AF%E7%89%87%E4%B8%AD%E6%96%87%E7%A4%BE%E5%8C%BA/FS6523%E8%8A%AF%E7%89%87/m-p/1667948#M99 <P>意思就是LBIST失败了RSTB一样会release但是FS0B/FS1B就不能释放了，这样MCU方面也可以正常启动</P> Tue, 13 Jun 2023 05:56:09 GMT https://community.nxp.com/t5/%E7%94%B5%E6%BA%90%E7%AE%A1%E7%90%86%E8%8A%AF%E7%89%87%E4%B8%AD%E6%96%87%E7%A4%BE%E5%8C%BA/FS6523%E8%8A%AF%E7%89%87/m-p/1667948#M99 guoweisun 2023-06-13T05:56:09Z https://community.nxp.com/t5/%E7%94%B5%E6%BA%90%E7%AE%A1%E7%90%86%E8%8A%AF%E7%89%87%E4%B8%AD%E6%96%87%E7%A4%BE%E5%8C%BA/FS6523%E8%8A%AF%E7%89%87/m-p/1667958#M100 <P>好的，明白了，谢谢您！</P> Tue, 13 Jun 2023 06:03:26 GMT https://community.nxp.com/t5/%E7%94%B5%E6%BA%90%E7%AE%A1%E7%90%86%E8%8A%AF%E7%89%87%E4%B8%AD%E6%96%87%E7%A4%BE%E5%8C%BA/FS6523%E8%8A%AF%E7%89%87/m-p/1667958#M100 jiadian666 2023-06-13T06:03:26Z
