NRF52 SPIM current

[yaron]

Hi

I am using nrf52832 QFAA-R. I wanted to know if there is a difference between SPIM current when SPIM is:

1. stopeed
2. started but not active.

Thanks Yaron

Hi,

1. When SPIM is stopped and the STOPPED event has been received, then it should not be consuming any current.

2. This is given in the spec

   SPIM,IDLE Idle current for SPIM (STARTed, no CSN activity) = 1 µA

More details can be found in infocenter SPIM electrical spec

Do you mean that a transaction has stoppen, but the peripheral is enabled?

What does started but not active mean? Do you mean enabled but that no transaction have been started?

This means that the actions under "Low Power SPI master" given here are unnecessary for NRF52? I keep getting busy errors when trying to transfer after enabling/disable the interfaces.
