Feature (1)
F0h
Features code F0h enables the host to configure the card to test card function. The host sets a value C0h
in the Sector Count register that is permission physical sector access.
The Physical Read Sector command performs similarly to the Read Sector(s) command except that it
returns 528 bytes from physical sector (flash page). During a Physical Read Sector command, the PC
Card does not check the ECC bytes to determine if there has been a data error. Only single sector Read
long operations are supported. The transfer consists of 512 bytes of data transferred in word mode
followed by 16 bytes of spare data transferred in byte mode. This command has the same protocol as the
Read Sector(s) command. Use of this command is Developer’s test.
