USB Stellaris Lib for C6748

Hi,

I am using Stellaris USB lib with DMA.

In file cppi41dma.c  there is "CppiDmaGetINTD0Status" function.

Inside the fucntion there is a read from register called and define as "CPDMA_INTD_0_REGISTER", register's address is usbOtgBase + 0x3200,

I really can't find this register maybe there is some error?

I had some interrupt issues with USB so this could help, please clarify  what it's exact address and what is register's name? 

Thanks

Dani
