UDC Interruption Enable Register (UDCIE)

The UDC interrupt enable register (UDCIE) is a register that allows each interrupt factor
in the UDC status register to be raised as an interrupt bit wisely except CONFN.

The function of each bit in the UDC interrupt enable register (UDCIE) is described in the following.
[bit15, bit14] Reserved bits
It is reserved bit. Please write "00
[bit13] SUSPIE: Suspend interrupt enable bit
It allows an interrupt due to the interrupt factor for the UDC status register "SUSP" to be generated.
