I am thining of to use STM32 to communicate with MIPI interface. Please see the typical format in the attachment. It is hard to do that with PIC18F controller, for data rate up to 26MHz; by-directional TX/RX SPI like data from 1 pin; 23 clocks's data for TX and 24 clocks's data for RX.

Can it be done on STM32? #23-is-prime

Awesome, a ''standard'' protocol that isn't easy to implement with existing micro controllers, if it were using 24 clocks, SPI would be a candidate, but 23-bits, got to be the work of a genius.

The STM32 only permits SPI widths of 8 or 16 bits. So no, short of using a PLD probably not. 26 MHz will likely require setting the CPU frequency to some multiple of that.
