USB Interrupt Acknowledge Register – UIAR
Bit 7 – SOF INTACK: Start of Frame Interrupt Acknowledge
The microcontroller firmware writes a 1 to this bit to clear the SOF INT bit.
Bit 6 – EOF2 INTACK: EOF2 Interrupt Acknowledge
The microcontroller firmware writes a 1 to this bit to clear the EOF2 INT bit.
Bit 5 – Res: Reserved bit
This bit is reserved and is always read as zero.
Bit 4 – FEP3 INTACK: Function End-point 3 Interrupt Acknowledge
The microcontroller firmware writes a 1 to this bit to clear the FEP3 INT bit.
Bit 3 – HEP0 INTACK: Hub Endpoint 0 Interrupt Acknowledge
The microcontroller firmware writes a 1 to this bit to clear the HEP0 INT bit.
Bit 2 – FEP2 INTACK: Function Endpoint 2 Interrupt Acknowledge
The microcontroller firmware writes a 1 to this bit to clear the FEP2 bit.
Bit 1 – FEP1 INTACK: Function Endpoint 1 Interrupt Acknowledge
The microcontroller firmware writes a 1 to this bit to clear the FEP1 bit.
Bit 0 – FEP0 INTACK: Function Endpoint 0 Interrupt Acknowledge
The microcontroller firmware writes a 1 to this bit to clear the FEP0 INT bit.
