Endpoint OUT Receive Decrement Register.
No. of packets that have been transferred from the host RX
DMA buffer. Updated by firmware.
Endpoint OUT Receive Pending Register.
No. of received packets that have been transferred to the
host RX DMA buffer by the USB DMA DMAC channel.
Note: No new packets will be transferred if
EP_OUT_PEND = EP_BUFSIZE.
Total Received Packet Size.
Should be less than or equal 226, should match with value
programmed into DMAC_12_Cnt1 register minus one count.
Using the following formula given the USB RX DMA Size
(DMA_SIZE) in bytes, DMA_SIZE < = 16376 and a multiple
integer number of 72
DMAC_12_Cnt1 = (DMA_SIZE / 8)
Count value = ((DMA_SIZE) / 72) -1
Receive qword Count Register.
Used by hardware.
