SOF/EOP Interrupt Flag (Bit 9)
The SOF/EOP Interrupt Flag bit indicates the status of the
SOF/EOP Timer interrupt. This bit triggers ‘1’ when the
SOF/EOP timer expires.
1: Interrupt triggered
0: Interrupt did not trigger
Port B Wake Interrupt Flag (Bit 7)
The Port B Wake Interrupt Flag bit indicates remote wakeup
on PortB.
1: Interrupt triggered
0: Interrupt did not trigger
Port A Wake Interrupt Flag (Bit 6)
The Port A Wake Interrupt Flag bit indicates remote wakeup
on PortA.
1: Interrupt triggered
0: Interrupt did not trigger
Port B Connect Change Interrupt Flag (Bit 5)
The Port B Connect Change Interrupt Flag bit indicates the
status of the Connect Change interrupt on Port B. This bit
triggers ‘1’ on either a rising edge or falling edge of a USB
Reset condition (device inserted or removed). Together with
the Port B SE0 Status bit, it can be determined whether a
device was inserted or removed.
1: Interrupt triggered
0: Interrupt did not trigger
Port A Connect Change Interrupt Flag (Bit 4)
The Port A Connect Change Interrupt Flag bit indicates the
status of the Connect Change interrupt on Port A. This bit
Host n SOF/EOP Count Register [R/W]
Register Description
The Host n SOF/EOP Count Register contains the SOF/EOP
Count Value that is loaded into the SOF/EOP counter. This
value is loaded each time the SOF/EOP counter counts down
to zero. The default value set in this register at power up is
0x2EE0 which generates a 1-ms time frame. The SOF/EOP
counter is a down counter decremented at a 12-MHz rate.

triggers ‘1’ on either a rising edge or falling edge of a USB
Reset condition (device inserted or removed). Together with
the Port A SE0 Status bit, it can be determined whether a
device was inserted or removed.
1: Interrupt triggered
0: Interrupt did not trigger
Port B SE0 Status (Bit 3)
The Port B SE0 Status bit indicates if Port B is in a SE0 state
or not. Together with the Port B Connect Change Interrupt Flag
bit, it can be determined whether a device was inserted
(non-SE0 condition) or removed (SE0 condition).
1: SE0 condition
0: Non-SE0 condition
Port A SE0 Status (Bit 2)
The Port A SE0 Status bit indicates if Port A is in a SE0 state
or not. Together with the Port A Connect change Interrupt Flag
bit, it can be determined whether a device was inserted
(non-SE0 condition) or removed (SE0 condition).
1: SE0 condition
0: Non-SE0 condition
Done Interrupt Flag (Bit 0)
The Done Interrupt Flag bit indicates the status of the USB
Transfer Done interrupt. The USB Transfer Done triggers
when either the host responds with an ACK, or a device
responds with any of the following: ACK, NAK, STALL, or
Timeout. This interrupt is used for both Port A and Port B.
1: Interrupt triggered
0: Interrupt did not trigger
When this register is read, the value returned is the
programmed SOF/EOP count value.
Count (Bits [13:0])
The Count field sets the SOF/EOP counter duration.
Reserved
All reserved bits should be written as ‘0’.
