5.1.4 Auto Power Saving Mode
If host does not issue any command during a certain duration (1ms), after previously issued command is completed, the device enters "Power Saving
mode" to reduce power consumption.
At this time, commands arriving at the device while it is in power saving mode will be serviced in normal fashion

6.0 REGISTER VALUE
6.1 OCR Register
The 32-bit operation conditions register stores the VDD voltage profile of the e·MMC. In addition, this register includes a status information bit. This status
bit is set if the e·MMC power up procedure has been finished. The OCR register shall be implemented by all e·MMCs.
[Table 30] OCR Register
NOTE :
1) This bit is set to LOW if the e·MMC has not finished the power up routine
2) The voltage for internal flash memory(VDDF) should be 2.7-3.6v regardless of OCR Register value.
6.2 CID Register
[Table 31] CID Register
NOTE :
1),4),5) description are same as e.MMC JEDEC standard
2) PRV is composed of the revision count of controller and the revision count of F/W patch
3) A 32 bits unsigned binary integer. (Random Number)

6.3 CSD Register
The Card-Specific Data register provides information on how to access the e·MMC contents. The CSD defines the data format, error correction type, max-
imum data access time, data transfer speed, whether the DSR register can be used etc. The programmable part of the register (entries marked by W or
E, see below) can be changed by CMD27. The type of the entries in the table below is coded as follows:
R : Read only
W: One time programmable and not readable.
R/W: One time programmable and readable.
W/E : Multiple writable with value kept after power failure, H/W reset assertion and any CMD0 reset and not readable.
R/W/E: Multiple writable with value kept after power failure, H/W reset assertion and any CMD0 reset and readable.
R/W/C_P: Writable after value cleared by power failure and HW/ rest assertion (the value not cleared by CMD0 reset) and readable.
R/W/E_P: Multiple writable with value reset after power failure, H/W reset assertion and any CMD0 reset and readable.
W/E/_P: Multiple wtitable with value reset after power failure, H/W reset assertion and any CMD0 reset and not readable.
