MuxOneNAND2G(KFM2G16Q2A-DEBx)
6.17 Cold Reset Timing
NOTE :
1) Bootcode copy operation starts 400us later than POR activation.
2) 1K bytes Bootcode copy takes 70us(estimated) from sector0 and sector1/page0/block0 of NAND Flash array to BootRAM.
3) INT register goes ‘Low’ to ‘High’ on the condition of ‘Bootcode-copy done’ and RP rising edge.
MuxOneNAND4G(KFN4G16Q2A-DEBx)
System Power
MuxOneNAND
The system power should reach Vcc after POR triggering level(typ. 1.5V) within 400us for valid boot code data.
Host can read Bootcode in BootRAM(1K bytes) after Bootcode copy completion.
If RP goes ‘Low’ to ‘High’ before ‘Bootcode-copy done’, INT register goes to ‘Low’ to ‘High’ as soon as ‘Bootcode-copy done’
