Boot up
|

The Jz4740 can be set to boot from NOR or NAND.
|

If booted from NAND, the CPU fetches the first page from NAND and uses the first 4 bytes on it to know how the NAND chip should be treated (16/8-bit bus, 2/3 row cycles).
|

After that it copies the first 8kB from NAND and copies it to the I-Cache for execution.
