Hello,

the framing error indicates in Master and 4 wire SPI-Mode a falling edge on STE, indicating a BUS conflict.

Best regards

Hello Al,

one of the documents, where you can find a description on it is the MSP430F1xx User's Guide

I know this is a different MSP430 family, but we kept the feature the same for compatibility reasons. You can find the statements on page 14-5.

The corresponding section in the MSP430FR59xx/69xx UG is 31.3.3.1 4-Pin SPI Master Mode (UCSTEM = 0). Unfortunately the description does not sound as clear. It takes 20y of MSP430 history and experience.

Best regards

Peter

Hi Alex,

based on your feedback I assume the case is closed thus closing the thread. For future cases a small hint. Answering to a post, where you clicked on "This resolved my issue", re-opens the thread. Thus the recommendation is, 1st post your final answer and then click on "Resolved..." Many thanks in advance.

For this time I am closing it from my side.

Best regards

Peter
