Readout Protecion F2MC-16FX MB96F340

[GaSz_4610156]

Hello Community,

I'm reading this document:

Microsoft Word - mcu-an-300213-e-v13-16fx_flash_security.doc (fujitsu.com)

In section 2.1 the document sais:

'[...] If the supplied Unlock Key is all 0, the Flash Security cannot be disabled at all.'

My question is: If I set the Unlock Key fully with zeros, then will I be able to perform a Chip Erase with the CYPRESS FLASH MCU Programmer after this full-zero setting is applied?

Thank in advance,

Gabor
