Hub Port Status
Register
The bits in this register are used by the microcontroller firmware when reporting a port's status
through the Port Status Field,
wPortStatus
. Bits 3 (POCI) and 5 (PPSTAT) are used by the
USB hardware and are the only two bits that the firmware should set or clear. All other bits
should not be modified by the firmware.
Hub Port Status Register – HPSTAT2, 3
Bit 7 – Reserved
This bit is reserved in the AT43USB326 and will read as zero.
Bit 6 – LSP: Low-speed Device Attached
0 = Full-speed device attached to this port
1 = Slow-speed device attached to this port
Set to 0 for Port 1 (full-speed only). Set and cleared by the hardware upon detection of device
at EOF2.
Bit 5 – PPSTAT: Port Power Status
0 = Port is powered OFF
1 = Port is powered ON
Set to 1 for Port 1. Set and cleared based on present status of port power.
Bit 4 – PRSTAT: Port Reset Status
0 = Reset signaling not asserted
1 = Reset signaling asserted
Set and cleared by the hardware as a result of initiating a port reset by Port Control Register.
Bit 3 – POCI: Port Overcurrent Indicator
0 = Power normal
1 = Overcurrent exist on port
Set to 0 for Port 1. Set and cleared by firmware upon detection of an overcurrent or removal of
an overcurrent.
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
