For IN endpoints, incremented after each byte written by the software into the endpoint and decremented after each byte
sent to the host.
For OUT endpoints, incremented after each byte received from the host and decremented after each byte read by the soft-
ware from the endpoint.
Note that this field may be updated 1 clock cycle after the RWALL bit changes, so the user should not poll this field as an
interrupt flag.
