Argument of a command or data field.
MultiMediaCard bus command <n>. See Command.
Push Pull, output driver type with low impedance driver capability for 0 and 1.
Open Drain, output driver type with low impedance driver capability for 0 and high
impedance driver capability for 1.
Card specific data, MultiMediaCard register to store operating parameters.
Card identification data, MultiMediaCard register for the card initialization procedure.
Relative card address, MultiMediaCard register which contains the current card
address of an initialized MultiMediaCard.
Operation condition register, MultiMediaCard register that contains the voltage window
which is supported by the MultiMediaCard.
Driver stage register, control register for the programmable driver stage driver (PDS).
Programmable driver stage driver, is a tri-state output driver which has is
programmable to adapt the driver capabilities to the bus design.
A command send from the MultiMediaCard host to one or more MultiMediaCard cards
A response is always sent from the card to the host. It is always initiated by a
command (Remark: not all commands enforce responses).
A command may send as broadcast or as an addressed command. A broadcast
command is sent to all cards connected to the MultiMediaCard bus simultaneous.
An addressed command is sent to exactly one selected MultiMediaCard. Normally an
addressed command forces a response of the card.
Same as addressed command
The data (input)/output signal of the MultiMediaCard.
The clk input signal of the MultiMediaCard.
The command/response input/output of the MultiMediaCard.
Ground contacts/lines of the MultiMediaCard.
Supply voltage contact/line of the MultiMediaCard.
Array of memory cells in the core of the MultiMediaCard.
MultiMediaCard command interpreter module.
