nrf54L15 SPIM PSEL.CSN

[Ingfu]

Hi,

the nrf54L15 datasheet states on SPIM "CSN and DCX are not present in all configuration" (p.559). But I can't find the information, when CSN is available.

Hi Ingfu, 

The sentence means not all SPIM instances have the CSN and DCX supported. 
The issue is that we don't have the info about that in the Configuration section in SPIM chapter. 
I have reported this internally hopefully it will be fixed soon. 
For the time being, you can take a look at Pin assignments section and can find that SPIM00, SPIM20, SPIM21 have pin recommendation for CSN and DCX in the list. So you can be safe using them.

Hi, the datasheet v0.9 has been updated regarding the CSN. According to Configuration table on p. 564, all SPIM instances support CSN, is that correct? I am asking, because the data sheet still states "Chip select (CSN) hardware control is supported in some instances of SPIM".

Also, the table is contradictoy:

Where do I claim my free DKs for doing your proof reading?

Hi Florian, 
Thanks for doing the hardwork :) The datasheet is still on version 0.x so there is still a lot of thing to improve and clean up :) 

Regarding the the table, what you meant is the duplication of 
DCX and CSN is supported.
CSN functionality is supported.
DCX functionality is supported.

correct ?

Hi Hung,

what I meant is:

SPIM22

DCX and CSN is supported.
CSN functionality is supported.
DCX functionality is not supported.

I see, thanks. It's now reported.
