A0h-A7h: Device Power Configuration
The USB224x has one internal FET which can be utilized for card power. This section describes the
default internal configuration. The settings are stored in NVSTORE and provide the following features:
1. A card can be powered by an external FET or by an internal FET.
2. The power limit can be set to 100 mA or 200 mA (Default) for the internal FET.
Each media uses two bytes to store its device power configuration. Bit 3 selects between internal or
external card power FET options. For internal FET card power control, bits 0 through 2 are used to
set the power limit. The “Device Power Configuration” bits are ignored unless the “Enable Device
