6.4 Extended CSD Register
The Extended CSD register defines the e·MMC properties and selected modes. It is 512 bytes long.
The most significant 320 bytes are the Properties segment, which defines the e·MMC capabilities and cannot be modified by the host. The lower 192
bytes are the Modes segment, which defines the configuration the e·MMC is working in. These modes can be changed by the host by means of the
SWITCH command.
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
