(20) UF0 INT mask 4 register (UF0IM4)
This register controls masking of the interrupt sources indicated by the UF0IS4 register.

of this register.
The related bits are invalid if each endpoint is not supported by the setting of the UF0EnIM register (n = 1, 2)
and the current setting of the interface.
