5.4.2 Bus Operating Conditions
General
Power Supply Voltage - High Voltage MultiMediaCard
Power Supply Voltage - Dual voltage MultiMediaCard
The current consumption of the card for the different card configurations is defined in the power class fields in the
EXT_CSD register.
The current consumption of any card during the power-up procedure, while the host has not sent yet a valid OCR range,
must not exceed 10 mA
