OFIFO2n
There are two register, OFIFO1n and OFIFO2n, which maintain the write count. OFIFO1n maintains the
lower bytes, while OFIFO2n maintains the higher byte. When ORDY bit of OCSR1n is set for OUT
endpoints, these registers maintain the number of bytes in the packet due to be unloaded by the MCU.
