Operation
Note: 1) Bootcode copy operation starts 400us later than POR activation.
The system power should reach 1.7V after POR triggering level(typ. 1.5V) within 400us for valid boot code data.
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’

8.3 Reset Mode
8.3.1 Cold Reset
At system power-up, the voltage detector in the device detects the rising edge of Vcc and releases internal power-up reset signal
which triggers bootcode loading. Bootcode loading means that the boot loader in the device copies designated sized data(1KB) from
the beginning of memory to the BootRAM.
