Start boot mode: Delete block, write data into on-chip flash

Latest Updated:04/19/2013

Question:

Is it necessary to delete the block using block erase command before writing the data into the on-chip flash with the program command when starting the boot mode?

Answer:

When starting the boot mode, all blocks of the on-chip flash will be erased automatically before transit to the wait state for program/erase/other commands. Therefore, the erasing operation for the block before writing the first data is not required.
