The SPI frame about MC33978 is 32 bits size, but MPC5604B DSPI transfer frame size is ony 16 bits. How to configure it?</P><P></P><P>Please help me, thanks!</P></BODY></HTML> Tue, 14 Nov 2017 02:17:24 GMT https://community.nxp.com/t5/MPC5xxx/How-does-MPC5604B-transmit-32-bits-size-frame-about-SPI/m-p/767672#M10991 jeffcharles 2017-11-14T02:17:24Z Re: How does MPC5604B transmit 32 bits size frame about SPI https://community.nxp.com/t5/MPC5xxx/How-does-MPC5604B-transmit-32-bits-size-frame-about-SPI/m-p/767673#M10992 <HTML><HEAD></HEAD><BODY><P>Use two 16-bit frames.
