Flash Memory
44.1.1.1
FLASH: Flash Erase Issue
Performing a Flash erase with the ERASE pin can put the device into an unrecoverable non
functional mode.
Please note that using any software erase commands
(EFC) does not affect the device behavior.
Problem Fix/Workaround
To erase the Flash memory with the ERASE pin, the following sequence must be applied:
• Assert the ERASE pin to a high level
• Wait 10 seconds
• Power down and power up the device
After this sequence, the Flash memory can be programmed and GPNVM or lock bits can be pro-
grammed according to the application needs.
