6.2.1 Flash Signal Descriptions
– Write Protect (nwp)
Write protect is an input that gives an additional hardware protection for each block. When Write Protect
is ≤ 0.4V the Lock-Down is enabled and the protection status of the flash blocks cannot be changed.
When Write Protect is ≥ (vddq - 0.4V), the Lock-Down is disabled and the flash memory blocks can be
locked or unlocked.
– Reset (nrp)
The Reset input provides a hardware reset of the memory. When reset is ≤ 0.4V, the memory is in reset
mode: the outputs are high impedant and the current consumption is minimized. After Reset all blocks
are in Locked state. When Reset is ≥ (vddq - 0.4V), the device is in normal operation. Exiting reset mode
