MCXN94X Random Number Generator

Dear NXP Support,

on most block diagrams of the MCXN MCUs, e.g. MCX-N94X-N54X.pdf, there is a Random Number Generator (TRNG) Block. In the Datasheet and Reference Manual there is no further information on RNG Block. Could you please clarify - is there a hardware RNG Block in MCXN MCUs?

Best Regards
