Power on
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 the HB288032MM1 works properly but the access to the memory core is not guaranteed. So in
the power up phase (or when the HB288032MM1 is 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:
