The maximum supported frequency depends on host driver capabilities (data latching edge, setup time, hold time, clock jitter, clock duty-cycle, IO delay etc.) and the system level design (PCB design, propagation delay, IO load etc.). Timing analysis for the complete path (Host to Device) needs to be performed for determining the maximum achievable frequency.
An indicative example: Supported frequency of Radar SPI Peripheral mode is 40MHz in full cycle and 20MHz in half cycle mode.
