3.12.1.4 PI Update

Once new partition information is programmed into the PI block, an internal register that is invisible to users must be updated for the changes in PI to be applied. This internal register which stores partition information(i.e. the last address of SLC area and lock bits) will be automatically updated through cold reset. However, the internal register can also be updated by issuing Partition Information Update command(05h) after PI Access mode entry.

Update the PI Area

•Issue the PI Access mode(Refer to Chapter 3.12.1.1).

•Issue the update PI command.

PI Block Update (In PI Block Access Mode)

Start

Write ‘DFS, FBA’ of Flash1)

Add: F100h DQ=DFS, FBA

Write ‘BSA, BSC’ of DataRAM

Add: F200h DQ=0800h2)

Write 0 to interrupt register3)

Add: F241h DQ=0000h

Write ‘FPA, FSA’ of Flash

Add: F107h DQ=0000h4)

Write Update PI command

Add: F220h

DQ=0005h

Wait for INT register low to high transition

Add: F241h DQ[15]=INT

PI updated

* DBS, DFS is for DDP

NOTE :

1)FBA(NAND Flash Block Address) must be 0000h.

2)BSA must be 1000 and BSC must be 000.

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

4)FPA must be 00h and FSA must be 00.
