Conflict between SPI1 and TWI1 on nRF51

[kilianod]

Hello

I've been having some strange problems with my SPI and TWI bus. In my setup, I'm using SPI0 and TWI1. I noticed that, even though I'm not using it, that SPI1 was consuming a lot of power so I disabled it with NRF_SPI0->ENABLE = 0;.

Now I seem to be having problems with my TWI1 bus, it stops working sometimes when SPI1 is disabled, why is this happening? Are they somehow related? Or how do I stop the SPI1 bus from consuming power when I'm not using it?

Thanks

I think that SPI1 and TWI1 use shared hardware, I do not have the product specification in hand but their base addresses are same as far as i can remember. Do not disable SPI1 when you are using TWI1
