Two other SSPs (0,2) work fine and can be configured to any modes.&nbsp; </SPAN><BR /><BR /><SPAN>No description in errata for that. How it is possible, the bug like that was not identified?</SPAN><BR /><BR /><SPAN>Did anybody come across this issue? Weird, the only comment I can have. </SPAN><BR /><BR /><SPAN>Thanks, Regards, </SPAN><BR /><SPAN>Piotr.</SPAN><BR /><BR /><BR /></BODY></HTML> Wed, 15 Jun 2016 17:45:43 GMT https://community.nxp.com/t5/LPC-Microcontrollers/LPC1778-SSP1-works-only-in-Microwire-mode/m-p/520546#M3687 lpcware 2016-06-15T17:45:43Z Re: LPC1778 - SSP1 works only in Microwire mode!!! https://community.nxp.com/t5/LPC-Microcontrollers/LPC1778-SSP1-works-only-in-Microwire-mode/m-p/520547#M3688 <HTML><HEAD></HEAD><BODY><STRONG>Content originally posted in LPCWare by xianghuiwang on Fri Aug 15 17:05:00 MST 2014</STRONG><BR /><SPAN>hi, michcior,</SPAN><BR /><BR /><SPAN>this is weird.
