AT43USB325
Bit 2 – PSSTAT: Port Suspend Status
0 = Port not suspended
1 = Port suspended
Set and cleared by the hardware as controlled through Port Control Register.
Bit 1 – PESTAT: Port Enable Status
0 = Port is disabled
1 = Port is enabled
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 AT43USB325 and will read as zero.
Bit 2
–
OVC 2
Setting this bit enables the hub to detect an overcurrent on a port while the hub is in the suspend
state. The overcurrent condition is signalled by a 1 to 0 transition at PD0.
