Bit 15:

This bit indicates that an odd packet is received at endpoint 4.

Bit 14:

This bit indicates that an odd packet is received at endpoint 2.

Bit 13:

When it is “1”, it indicates that the device is in suspend mode. If the

PC does a global wake up, this bit will be reset to “0”. The firmware

can reset this bit to ”0” by performing a device remote wakeup (setting

the resume bit to be “1” in USBClrIRQ register).

Bit 12:

This bit indicates that if the control write on endpoint 5 is successful.

“1” – Ack. “0” – Nack.

Bit 11:

This bit indicates that if the control read on endpoint 5 is successful.

“1” – Ack. “0” – Nack.

Bit 10:

This bit indicates that if the control write on endpoint 0 is successful.

“1” – Ack. “0” – Nack.

Bit 9:

This bit indicates that if the control read on endpoint 0 is successful.

“1” – Ack. “0” – Nack.

Bit 8:

This bit indicates that a USB reset is detected on the bus.

Bit 7:

This bit indicates a suspend is detected on the bus.

Bit 6:

This bit indicates the DMA has reached its block size.

Bit 5:

This bit indicates that the endpoint 5 data buffer is full.

Bit 4:

This bit indicates that the data in endpoint 5 buffer has been send.

Bit 3:

This bit indicates that a set up packet has been send to endpoint 5

and the endpoint 5 setup data buffer is full.

Bit 2:

This bit indicates that the endpoint 0 data buffer is full.

Bit 1:

This bit indicates that the data in endpoint 0 buffer has been send.

Bit 0:

This bit indicates that a set up packet has been send to endpoint 5

and the endpoint 5 setup data buffer is full.
