Question

"Power ON or card insersion After supply voltage reached above 2.2

volts, wait for one millisecond at least. Set SPI clock rate between 100 kHz and 400 kHz. Set DI and CS high and apply 74 or more clock pulses to SCLK. The card will enter its native operating mode and go ready to accept native command."

"The host may reset the cards by switching the power supply off and on again. Each card shall have its own power-on detection circuitry thatputs the card into a defined state after the power-on. No explicit reset signal is necessary. The cards can also be reset by sending the GO_IDLE (CMD0) command."
