Attention for Card Use
• In the reset or power off, all register informations are cleared.
• All card status are cleared automatically when VCC 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 VCC can not be supplied to the card. After confirmation that -CD1, -CD2 pins are
inserted, supply VCC to the card.
• -OE must be kept at the VCC 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.
