Bus Signal Levels
80x Secure Digital Card
As the bus can be supplied with a variable supply voltage, all signal levels are related to the supply voltage.
To meet the requirements of the JEDEC specification JESD8-1A, the card input and output voltages shall be within the
following specified ranges for any V
