Description
Hi,
I believe I have found an issue with the NANO33 BLE REV2.
I am using Sense version but suspect this may affect standard version too.
Issue I have is that after using the SPI port to talk to an SD card, I am then no longer able to use GPIO pins even after SPI.end() has been called.
Identical code on Nano 33 IOT and original Nano allows access to GPIO after call to SPI.end().
It appears that NRF_SPIM2 enable register is not set to 0 by SPI.end() as such SPI is not disabled.
If I set manually set this 0 zero to disable the SPI, I can set the GPIO pins as desired.
Issue was raised on Arduino Forum:

Suggestion on forum was made to raise issue here.
