I have to do it before another transaction. But this is the best place to do it. Normally it there was not the bug I do init only once at the beginning of code. Since I need to do workaround I need to reinit again - so it is best to do it right after SPI power reset. Also I need to do uninit otherwise init would fail. Also note that this reset and reinit is not necessary when sending/receiving more bytes (and not using GPIOTE). In multiple bytes sending I do not do deinit,reset nor init.

EDIT: Errataum 89 with workaround is affecting:

TWIM1 and TWI2
SPIM0 and SPIM1 but not SPIM2.
none of the SPIS instances (SPIS0, SPIS1 or SPIS2).
none of the SPI instances (SPI0, SPI1 or SPI2).

I'll create an internal note to get the PAN updated.

Hi,

Is it so that you need to immediately reinitiate the driver to get the consumption down? Or is the point simply that you have to reinitiate it before you do another transaction?
