The downstream USB ports are designed for connection of USB devices, but can also serve as output ports under firmware
control. This allows unused USB ports to be used for functions such as driving LEDs or providing additional input signals. Pulling
up these pins to voltages above V
This register is not reset by USB bus reset. These bits must be cleared before going into suspend.
Table 16-1. Control Bit Definition for Downstream Ports
An alternate means of forcing the downstream ports is through the Hub Ports Force Low Register (Figure 16-5) Register. With
this register the pins of the downstream ports can be individually forced LOW, or left unforced. Unlike the Hub Downstream Ports
Control Register, above, the Force Low Register does not produce standard USB edge rate control on the forced pins. However,
this register allows downstream port pins to be held LOW in suspend. This register can be used to drive SE0 on all downstream
ports when unconfigured, as required in the USB 1.1 specification.
.
The data state of downstream ports can be read through the HUB Ports SE0 Status Register (Figure 16-6) and the Hub Ports
Data Register (Figure 16-7). The data read from the Hub Ports Data Register is the differential data only and is independent of
the settings of the Hub Ports Speed Register (Figure 16-2). When the SE0 condition is sensed on a downstream port, the
corresponding bits of the Hub Ports Data Register hold the last differential data state before the SE0. Hub Ports SE0 Status
Register and Hub Ports Data Register are cleared upon reset or bus reset
.
Bit [0..3]: Port x SE0 Status (where x = 1..4).
