PPI output

Hardware: BF561 dev kit

 

Hi,

 

I am trying to configure PPI0 to Tx mode, 1 internal frame sync.  I don't yet have hardware to check if it is working, so just using the development kit to check the code/signals.

 

One problem I'm seeing is that after the dma transfer is complete I do disable the PPI ( *pPPI0_CONTROL ^= ((uint16_t)PORT_EN); )

Doing this clears the entire PPI0 control register.  So next time i run the function i need to re-configure the register.

 

Any advice on this would be great,

 

thanks,

 

Matt
