Attention for Card Use
In the reset or power off, all register informations are cleared.
All card status are cleared automatically when V
CC
voltage turns below about 2.5V.
Notice that the card insertion/removal should not be executed while host is active, if the card is used in
True IDE mode.
After the card hard reset, soft reset, or power on reset, ATA reset, command applied the card cannot
access during +RDY/-BSY pin is "low" level. Flash card can’t be operated in this case.
Card removal or power off should not be done during internal operations. When the removal or power off
occurrs during internal operation, there is a possibility that data are lost.
Before the card insertion V
CC
can not be supplied to the card. After confirmation that -CD1, -CD2 pins are
inserted, supply V
CC
to the card.
-OE must be kept at the V
CC
level during power on reset in memory card mode and I/O card mode. -OE
must be kept constantly at the GND level in True IDE mode.
We recommend that a circuit to detect the level of power supply voltage be added to the host.
When a read error occurs, rewriting of the sector is recommended. This may avoid the error.
