AT43USB325
8.4.4.3
Hub Port State Register – HPSTAT2...5
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 AT43USB325 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.
8.4.4.4
Hub Port Status Change Register – PSCR1..5
The microcontroller firmware uses the bits in this register to monitor when a port status change
has occurred, which then gets reported to the host through the Port Change Field
wPortChange
.
Except for bit 3, the Port Overcurrent Indicator Change, the bits in this register are set by the
USB hardware. Otherwise, the firmware should only clear these bits.
Bit 7..5 – Reserved
These bits are reserved in the AT43USB325 and will read as zero.
Bit 4 – RSTSC: Port Reset Status Change
0 = No change
