Power Up Time
Host needs to keep power line level less than 0.5V and more than 1ms before power ramp up.
Power On or Power Cycle
Followings are requirements for Power on and Power cycle to assure a reliable SD Card hard reset.
(1) Voltage level shall be below 0.5V
(2) Duration shall be at least 1ms.
Power Supply Ramp Up
The power ramp up time is defined from 0.5V threshold level up to the operating supply voltage which is
stable between VDD (min.) and VDD (max.) and host can supply SDCLK.
Followings are recommendation of Power ramp up:
(1) Voltage of power ramp up should be monotonic as much as possible.
(2) The minimum ramp up time should be 0.1ms.
(3) The maximum ramp up time should be 35ms for 2.7-3.6V power supply.
