Read/Write check
Note :
ATAINIT is a Card Wizard utility that create a DOS partition on the FlashDisk card.
ATAINIT program(the System Soft Corp FDISK utility).
4.14 Load of CIS Card Information Structure DID Drive Identify Data
- The foundations of CIS are defined as the firmware of ARM7TDMI. (Definition of only 5V power supply.)
- When effective data as CIS does not have data in head block of a flash or flash is not mounted, data
defined as the firmware is loaded as CIS.
- When there is CIS developed to the flash (After CIS and DID are written), its data become effective,
CIS is read from a flash.
- DID is not defined in first stage.
- The write of CIS/DID and the code of rewriting are put on the first page of first block of a flash, and
access to other blocks is not performed (management TBL etc. is not changed).
- CIS/DID needs to be rewritten with the specification of a card.
- Concept figure (CIS/DID Load action).
4.15 Power On Error
