(24) UF0 INT clear 3 register (UF0IC3)
UF0IC3
Bit position
This register controls clearing the interrupt sources indicated by the UF0IS3 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 UF0E2IM register and the
current setting of the interface.
