SPI peripheral is clocked by bus clock (60 MHz), and is limited to bus clock/2 (30 MHz), according to the reference manual. However, the datasheet states that, when operating in slave mode, there is a limitation of 15 MHz to the module frequency. Why is that? Is this really the maximum speed that I can get from the SPI as slave? I need a transfer rate of ~30Mbps as a slave. Is there any serial interface available in the MCU that I can achieve this (using FlexIO, for example)?
Thanks in advance,
