2.21 Users Must Not Set Page Lock in eNVM0 for the 060 Device and eNVM1 for 090/150 Devices

For 060, 090, and 150 device densities, each eNVM memory block has a user page lock bit (refer to PAGE_LOCK_SET register) to lock a page and prevent accidental writing. After the page lock is set in eNVM0 for the 060 device or eNVM1 for the 090/150 devices, the user will not be able to clear the lock for subsequent page updates later.

Workaround:

To use page lock feature, the user can use eNVM0 of 090/150 device and set/clear page lock using the master (for example, M3 or fabric). There is no workaround for the 060 device. User must contact SoC tech support if they already used page lock in the 060 device, which they need to unlock now.
