Hub General Registers
Global State Register – GLB_STATE
Bit 7...5 – Reserved Bits
These bits are reserved in the AT43USB320A and will read as zeros.
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.
