Please, confirm

my assumption: it is typing error in RM0090? Register DMA_SxFCR STM32F4xx

• Bits 1:0 FTH[1:0]: FIFO threshold selection

• These bits are set and cleared by software.

• 00: 1/4 full FIFO

• 01: 1/2 full FIFO

• 10: 3/4 full FIFO

• 11: full FIFO

• These bits are not used in the direct mode when the DMIS value is zero.

• These bits are protected and can be written only if EN is ‘1’

Must be EN = 0?P.S.

This is a Micro$oft product and it's very unlikely ST can do anything about it. Welcome to the club. Some of the frustration can be relieved by adding a ''worst forum software ever'' tag below... :) JW

. Not sure about that. Once ST had the choice, to either have a proper forum software, or something from Micro$oft. They still could migrate ... And while I don't like the above mentioned abuse NSA-bedfellow, there is more blame to put on ST. To use 'SharePoint' as user-forum software, is, euphemistically said, a little bit 'creative'.
