9.8.2
Using an external OC detection circuit
When V
CC
(pin 56) is connected to a 3.3 V instead of the 5 V power supply, the
internal OC detection circuit cannot be used. An external OC detection circuit must be
used instead. Regardless of the V
CC
value, an external OC detection circuit can
always be used. To use an external OC detection circuit, AnalogOCEnable, bit 10 of
the HcHardwareConfiguration register, should be logic 0. By default after reset, this
bit is already logic 0; therefore, the HCD does not need to clear this bit.
Figure 27
shows how to use an external OC detection circuit.

9.9.1
HC suspended state
The HC can be put into suspended state by setting the HcControl register (01H to
read, 81H to write). See
Figure 14
for the HC’s flow of USB state changes.
’n’ represents the downstream port number (n = 1 or 2).
