(25) UF0 INT clear 4 register (UF0IC4)
This register controls clearing the interrupt sources indicated by the UF0IS4 register.
This register is write-only, in 8-bit units. If this register is read, the value FFH is read.
FW can clear an interrupt source by writing 0 to the corresponding bit of this register. Even a bit that is
automatically cleared to 0 by hardware can be cleared by FW before it is cleared by hardware. Writing 0 to a bit of
this register automatically sets the bit to 1. Writing 1 is invalid.
The related bits are invalid if each endpoint is not supported by the setting of the UF0EnIM register (n = 1 to 4, 7)
and the current setting of the interface.
