3.12.2 PI Block Load Operation

A PI Block Load Operation accesses the PI area and transfers identified content from the PI to the DataRAM on-chip buffer, thus making the

PI contents available to the Host.

The PI area is a separate part of the NAND Flash Array memory. It is accessed by issuing PI Access command(66h).

After being accessed with the PI Access Command, the contents of PI memory area are loaded using the same operations as a normal load

operation to the NAND Flash Array memory (see section 3.6 for more information).

To exit the PI access mode after an PI Block Load Operation, a Cold-, Warm-, Hot-, or NAND Flash Core Reset operation is performed.

PI Block Read Operation Flow Chart (In PI Block Access Mode)

NOTE :

1) FBA(NAND Flash Block Address) could be omitted or any address.

2) ‘Write 0 to interrupt register’ step may be ignored when using INT auto mode. Refer to chapter 2.8.18.1

3) BSA must be 1000.
