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 Hitachi Mobile Embedded Flash.
Operation condition register, MultiMediaCard register that contains the voltage window
which is supported by these Hitachi Mobile Embedded Flashes.
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 Hitachi Mobile
Embedded Flashes
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 Hitachi Mobile Embedded
Flash. Normally an addressed command forces a response of the card.
