9.1

Check Power mode command (98h or E5h)

This command checks the power mode.

Issuing the command while the card is in Standby mode, is about to enter Standby, or is

exiting Standby, the command will set BSY, set the Sector Count register to 00h, clear BSY

and generate an interrupt.

Issuing the command when the card is in Idle mode will set BSY, set the Sector Count

register to FFh, clear BSY and generate an interrupt.

Table 47 defines the byte sequence of the Check Power mode command.
