WebI don't think this is the case. In slave mode, maximum input frequency is fPCLK/2, regardless of baudrate setting. However, specifically in TI mode (and that appears to be selected in the OP), the baudrate setting determines the timing for threestating MISO, see the SPI chapter, SPI TI protocol in slave mode subchapter, in RM . JW Web1 Apr 2024 · fPCLK is the input clock frequency and it can be maximum 40MHz. you may look into the document to know how to set the remaining timers. In the datasheet below, …
