3.16.3.8 Setup Received Register
This register informs for the UDC that an application program recognized
INT_SETUP interrupt.

If this register is accessed by an application program, the UDC release to disabling
access to EP0’s FIFO RAM because the UDC recognized the device request is received.
This is to protect data stored in EP0 in the time from continuous request has been
asserted to an application program recognized INT_SETUP interrupt.
Therefore, write “00H” to this register when the device request in INT_SETUP
routine is recognized.
Note : When EP0_FIFO is accessed register after wrote to this register, the recovery time of 2clock at 12MHz is
needed.
