Note: 1) Bootcode copy operation starts after 400us from the moment that Vcc reaches 2.5V.
2) 1K bytes Bootcode copy takes 70us(estimated) from sector0 and sector1/page0/block0 of NAND Flash array to BootRAM.
Host can read Bootcode in BootRAM(1K bytes) after Bootcode copy completion.
3) INT register goes ‘Low’ to ‘High’ on the condition of ‘Bootcode-copy done’ and RP rising edge.
If RP goes ‘Low’ to ‘High’ before ‘Bootcode-copy done’, INT register goes to ‘Low’ to ‘High’ as soon as ‘Bootcode-copy done’
