10.11.9 DEV_EPO_XFER_CNT
OUT Endpoint Remaining Transfer Length Register
There are 16 DEV_EPO_XFER_CNT registers. The address of each is calculated as DEV_EPO_XFER_CNT(x) = 0xE-
00314D8 + (x*0x4). Hence DEV_EPO_XFER_CNT(0) is at address 0xE00314D8, DEV_EPO_XFER_CNT(1) is at address
0xE00314D8 + 0x4 and so on. The definition of each of these is the same.
This register counts down the remaining bytes left in the transfer.
23:0 BYTES_REMAINING[23:0] Number of bytes remaining in the transfer. This value will never go negative (if more bytes are trans-
ferred than remaining in counter, counter value stays at 0).
