Power on / off
Each card has its own power on detection circuitry which puts the card into a defined state after the power-
on. No explicit reset signal is necessary. The cards can also be reset by a special software command:
GO_IDLE_STATE (CMD0). In case of emergency the host may also reset the cards by switching the
power supply off and on again.

Power on Detection
A power on reset is generated on chip as long as V
CC
is below a certain limit. After this reset the command
parser of these Renesas MultiMediaCards works properly but the access to the memory core is not
guaranteed. So in the power up phase (or when these Renesas MultiMediaCards are inserted during power
up) the host has to wait after sending SEND_OP_COND (CMD1) for the identification delay before the
ALL_SEND_CID (CMD2) can be interpreted by the card:
