STM32H523R PSSI clock configuration

Hello,

I’m trying to setup the PSSI interface on the STM32H523RETx to transmit data. I cannot find how is the PSSI_PDCK configure. Neither in the clock tree nor in the RCC register the PSSI clock can be configured (except for enabling it). In RM0481 table 305 the AHB clock is listed for PSSI_HCLK, but how is PSSI_PDCK generated?

Is it not possible to internally generate the clock? How is the requirement of AHB clock must be at least 2.5x PSSI_PDCK achieved?

In CubeMX (v6.14.1) I also couldn’t find any parameters for the PSSI clock.

Thanks!
