USB End-point
Interrupt Sources
An assertion or activation of one or more bits in the end-point's Control and Status Register
triggers the end-point interrupts. These triggers are different for control and non-control end-
points as described in the table below. Please refer to the Control and Status Register for
more information.
USB Interrupt Status Register – UISR
Bit 7 – SOF INT: Start of Frame Interrupt
This bit is asserted after the USB hardware receives a valid SOF packet.
Bit 6 – EOF2 INT: EOF2 Interrupt
This bit is asserted 10 clocks before the expected start of a frame.
Bit 5 – Res: Reserved Bit
This bit is reserved and always reads as zero.
Bit 4 – FEP3 INT: Function End-point 3 Interrupt
Bit 3 – HEP0 INT: Hub End-point 0 Interrupt
Bit 2 – FEP2 INT: Function End-point 2 Interrupt
Bit 1 – FEP1 INT: Function End-point 1 Interrupt
Bit 0 – FEP0 INT: Function End-point 0 Interrupt
The hub and function interrupt bits will be set by the hardware whenever the following bits in
the corresponding end-point's Control and Status Register are modified by the USB hardware:
1.
RX OUT Packet is set (control and OUT end-points)
2.
TX Packet Ready is cleared AND TX Complete is set (control and IN end-points)
3.
RX SETUP is set (control end-points only)
4.
TX Complete is set
