(2) UF0 EP0 length register (UF0E0L)
UF0E0L
The UF0E0L register stores the data length held by the UF0E0R register.
This register is read-only, in 8-bit units. A write access to this register is ignored.
The UF0E0L register always updates the length of the received data while it is receiving data. If the final transfer is
abnormal reception, the UF0E0L register is cleared to 0 and the interrupt request is not generated. The interrupt
request is generated only when the reception is normal, and the FW can read as many data from the UF0E0R
register as the value read from the UF0E0L register. The value of the UF0E0L register is decremented each time
the UF0E0R register has been read.
