Bit 7
–
Reserved Bit
This bit is reserved in the AT43USB325 and will read as zero.
Bit 6
–
KB INT EN: Keyboard Interrupt Enable
The firmware must set this bit to a 1 before entering suspend to allow remote wakeup when any
key depression is detected in the suspended state.
Bit 5
–
Reserved Bit
This bit is reserved in the AT43USB325 and will read as zero.
Bit 4
–
SUSP FLG: Suspend Flag
This bit is set to 1 while the USB hardware is in the suspended state. This bit is a firmware read
only bit. It is set and cleared by the USB hardware.
Bit 3
–
RESUME FLGL Resume Flag
When the USB hardware receives a resume signal from the upstream device it sets this bit. This
bit will stay set until the USB hardware completes the downstream resume signaling. This bit is a
firmware read only bit. It is set and cleared by the USB hardware.
Bit 2
–
RMWUPE: Remote Wakeup Enable
This bit is set if the host enables the hub's remote wakeup feature.
Bit 1
–
CONFG: Configured
This bit is set by firmware after a valid SET_CONFIGURATION request is received. It is cleared
by a reset or by a SET_CONFIGURATION with a value of 0.
Bit 0
–
HADD EN: Hub Address Enabled
This bit is set by firmware after the status phase of a SET_ADDRESS request transaction so the
hub will use the new address starting at the next transaction.
