nrf52840 write to external memory via qspi, initiated without cpu intervention

[ziv123]

hello Nordic

i am working with the nrf52840 dev kit, sdk 16.0 

i was wondering if it is possible to initiate a write via qspi, without cpu intervention (like when using ppi), only by entering a 16 bit value to some register or something like that ?

best regards

Ziv

You need to set up registers beforehand, but the writing task (TASK_WRITESTART) can be triggered by PPI.

Hello Ziv,

Turbo is correct here - you may initiate the transfer by connecting the TASK_WRITESTART to an event through PPI, but you would need to have to setup and configured the contents of the transfer beforehand.

Best regards,
