I am trying to get data from the slave but I noticed that the time between each frame is quite a lot (around 20us) which doesn't suite my application. I tried using interrupts as well but the time doesn't change that much. The frame size is 16 bits so the whole frame should take around 1us but I dont know where other 18-19us are wasted at. Does anybody have a clue? Am I missing something?</SPAN><BR /><BR /><SPAN>Taha </SPAN></BODY></HTML> Wed, 15 Jun 2016 18:49:12 GMT lpcware 2016-06-15T18:49:12Z SSP (SPI) Frame Timing https://community.nxp.com/t5/LPC-Microcontrollers/SSP-SPI-Frame-Timing/m-p/564956#M16982 <HTML><HEAD></HEAD><BODY><STRONG>Content originally posted in LPCWare by TahaSN on Fri Jan 03 15:07:30 MST 2014</STRONG><BR /><SPAN>Hello,</SPAN><BR /><BR /><SPAN>I am using LPC4350 (Hitex Board A4) and using SSP in SPI Mode with SCL Frequency of 20 MHz.
