Device Mode Registers Register Descriptions
doepint12
This register indicates the status of an endpoint with respect to USB- and AHB-related events. The
application must read this register when the OUT Endpoints Interrupt bit or IN Endpoints Interrupt bit of
the Core Interrupt register (GINTSTS.OEPInt or GINTSTS.IEPInt, respectively) is set. Before the
application can read this register, it must first read the Device All Endpoints Interrupt (DAINT) register to
get the exact endpoint number for the Device Endpoint-n Interrupt register. The application must clear the
appropriate bit in this register to clear the corresponding bits in the DAINT and GINTSTS registers.
doeptsiz12
The application must modify this register before enabling the endpoint. Once the endpoint is enabled
using Endpoint Enable bit of the Device Endpoint-n Control registers (DIEPCTLn.EPEna/
DOEPCTLn.EPEna), the core modifies this register. The application can only read this register once the
core has cleared the Endpoint Enable bit.
doepdma12
DMA OUT Address.
doepdmab12
DMA Buffer Address.
doepctl13
Out Endpoint 13.
