“0b01”: Monitor overcurrent for each port
individually.
Since this is the setting for a standard
ROM code product (003), a circuit that can
individually control overcurrent protection
functions externally is needed.
If this value is set for a Mask ROM code
when one of the pins CS1 to CS5 detect
overcurrent, Hub reports overcurrent on
per- port basis.
“0b1X”: Shows that there is no overcurrent
protection function. This setting is allowed
only for bus-powered hubs that do not
implement over-current protection.
If this value is set for a Mask ROM code
product, clamp all of the pins CS1 to CS5
to 3.3 V.
Bits 15-5:These bits are reserved in the USB
standard for future extended functions.
For a Mask ROM code product, be sure to
set these bits to “0”.
Caution Be sure to set the values in bits 3 and 0
the same in Mask ROM code product
settings.

bPowerOn2PwrGood
1
Shows the time from detecting a device at a port and
starting the power-on sequence until the power
supply stabilizes.
Two milliseconds are taken as one unit. This is 100
ms for the
μ
PD72012.

bHubContrCurrent
1
Shows the maximum current consumption of the
HUB in mA. Note that this value does not show the
rated current consumption value for the
μ
PD72012
itself.
For a standard ROM code product, “0x50” is applied
for compatibility with the
μ
PD72011. This value can
be defined for a Mask ROM code product. However,
this value should not be less than the current
consumption value of the
μ
PD72012 that is
described in 3. ELECTRICAL SPECIFICATIONS.
