Bit Bit Name Initial Value R/W Description
7 BRST 0 R/(W)
*
Bus Reset
Set to 1 when the bus reset signal is detected on the
USB bus. The corresponding interrupt output is
EXIRQ0 or EXIRQ1.
Note that BRST is also set to 1if D+ is not pulled-up
during USB cable connection.
6 — 0 R Reserved
This bit is always read as 0 and cannot be modified.
5 EP1iTR 0 R/(W)
*
EP1i Transfer Request
Set to 1 if there is no valid transmit data in the FIFO
when an IN token is sent from the host to EP1i. The
corresponding interrupt output is EXIRQ0 or EXIRQ1.
4 EP1iTS 0 R/(W)
*
EP1i Transfer Complete
Set to 1 if the transmit data written in EP1i is
transferred to the host normally and the ACK
handshake is returned. The corresponding interrupt
output is EXIRQ0 or EXIRQ1.
3
EP0oTS
0
R/(W)
*
EP0o Receive Complete
Set to 1 if the EP0o receives data from the host
normally and returns the ACK handshake to the host.
The corresponding interrupt output is EXIRQ0 or
EXIRQ1.
2
EP0iTR
0
R/(W)
*
EP0i Transmit Request
Set to 1 if there is no valid transmit data in the FIFO
when an IN token is sent from the host to EP0i. The
corresponding interrupt output is EXIRQ0 or EXIRQ1.
1
EP0iTS
0
R/(W)
*
EP0i Transmit Complete
Set to 1 if the transmit data written in EP0i is
transferred to the host normally and the ACK
handshake is returned. The corresponding interrupt
output is EXIRQ0 or EXIRQ1.
0
SetupTS
0
R/(W)
*
Setup Command Receive Complete
Set to 1 if the EP0s normally receives 8-byte data to
be decoded by the function from the host and returns
the ACK handshake to the host. The corresponding
interrupt output is EXIRQ0 or EXIRQ1.
Note: * The write value should always be 0 to clear this flag.
