AT43USB326
3313D–USB–04/06
Set and cleared by the hardware as controlled through Port Control register.
Bit 0 – PCSTAT: Port Connect Status
0 = No device on this port
1 = Device present on this port
Set to 1 for Port 1. Set and cleared by the hardware after sampling of connect status at EOF2.
Overcurrent Detect Register – UOVCER
Bit 7..3
–
Reserved
These bits are reserved in the AT43USB326 and will read as zero.
Bit 2
–
PORT 2
Setting this bit enables the hub to detect an overcurrent on Port 2 while the hub is in the sus-
pend state.
Bit 1, 0
–
Reserved
These bits are reserved in the AT43USB326 and will read as zero.
Hub Port State Register – HPSTAT2, 3
These registers contain the state of the ports’ DP and DM pins, which will be sent to the host
upon receipt of a GetBusState request.
Bit 7..2
–
Reserved
These bits are reserved in the AT43USB326 and will read as zero.
Bit 1
–
DPSTATE: DPlus State
Value of DP at last EOF. Set and cleared by hardware at EOF2.
Set to 1 for Port 1.
Bit 0
–
DMSTATE: DMinus State
Value of DM at last EOF. Set and cleared by hardware at EOF2.
Set to 0 for Port 1.
