5.4.4 Bus Signal Levels
As the bus can be supplied with a variable supply voltage, all signal levels are related to the supply voltage.
5.4.5 Open-Drain Mode Bus Signal Level
The input levels are identical with the push-pull mode bus signal levels.
5.4.6 Push-Pull Mode Bus Signal Level - High Voltage MultiMediaCard
To meet the requirements of the JEDEC specification JESD8-1A, the card input and output voltages shall be within the fol-
lowing specified ranges for any
5.4.7 Push-Pull Mode Bus Signal Level - Dual Voltage MultiMediaCard
The definition of the I/O signal levels for the Dual voltage MultiMediaCard changes as a function of
