NRF54L maximum SPI slave speed (SPIS)?

[Bruno Randolf]

I cannot find it in the documentation, so I'll ask here: What is the maximum clock frequency on NRF54L as a SPI slave?

Hi,

The maximum frequency for SPIS is 8 MHz. This is listed in the SPIS slave interface electrical specifications. (For other parameters, see Serial Peripheral Interface Slave (SPIS) timing specifications),

Interresting. I have already used it with up to 22MHz, but since that's out of spec, I guess I should go back down to 8MHz. Thank you!
