USB Endpoint Select Register (USEL)
Endpoints share the same XDATA space for FIFOs as well as the same SFR addresses
for Control and FIFO Valid Size registers. The USB Endpoint Select Register (see
Table
reading or writing to the FIFO XDATA address space. This register is also used to
select the direction and Endpoint when accessing the USB Endpoint Control Register.
