Register description
DMA address register (DMAR)
Bits 7:0=DA[15:8] DMA address bits 15-8.
Software must write the start address of the DMA memory area whose most significant bits
are given by DA15-DA6. The remaining 6 address bits are set by hardware. See the
description of the IDR register and
Interrupt/DMA register (IDR)
Bits 7:6 = DA[7:6] DMA address bits 7-6.
Software must reset these bits. See the description of the DMAR register and
Bits 5:4 = EP[1:0] Endpoint number (read-only). These bits identify the endpoint which
required attention.
