I expected 'SPI_TXDATCTL_LEN(8)' for 8 bit data length and needed a logic analyzer to find out that the LEN field in TXDATCTL is +1 encoded. More precisely: That the macro is +1 encoded as well.</P></BODY></HTML> Sun, 01 Sep 2019 08:23:45 GMT https://community.nxp.com/t5/LPC-Microcontrollers/LPC845-Wrong-value-in-SPI-TXDATCTL-EOT-flag/m-p/930614#M37099 1234567890 2019-09-01T08:23:45Z Re: LPC845: Wrong value in SPI | TXDATCTL | EOT flag https://community.nxp.com/t5/LPC-Microcontrollers/LPC845-Wrong-value-in-SPI-TXDATCTL-EOT-flag/m-p/930615#M37100 <HTML><HEAD></HEAD><BODY><P>Hello,</P><P>Thanks for your sharing.</P><P></P><P>BR</P><P>Alice</P></BODY></HTML> Mon, 02 Sep 2019 08:46:25 GMT https://community.nxp.com/t5/LPC-Microcontrollers/LPC845-Wrong-value-in-SPI-TXDATCTL-EOT-flag/m-p/930615#M37100 Alice_Yang 2019-09-02T08:46:25Z
