If this register is changed after packets have been sent from the endpoint, the transmit endpoint
FIFO must be completely flushed (using the FLUSH bit in USBTXCSRLn) after writing the new value
to this register.
Note: USBTXMAXPn must be set to an even number of bytes for proper interrupt generation in
µDMA Basic Mode.

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
