MDMA Error

Dear Sirs:

 

I meet a problem in using HDMA peripheral:

 

When I configure HDMA peripheral register correctly, the HDMA will work fine to read and write data.

 

But when I configure HDMA register uncorrectly, the HDMA will run into error, and the ALLOW_CNFG bit in HOST_STATUS will be always 0.

 

My question is how the host processor can reset the HDMA peripheral and make to work again?

 

Thanks for your help.

 

Jack
