Note: 1. Additional sectors to be erased must be entered within 80 µs. A Sector Address is any address within the Sector.

2. Flash and EEPROM Sector Selects are active high. Addresses A15-A12 are don’t cares in Instruction Bus Cycles.

3. The Reset instruction is required to return to the normal READ mode if DQ5 goes high or after reading the Flash Identifier or Pro-

tection status.

4. The MCU cannot invoke these instructions while executing code from EEPROM. The MCU must be operating from some other

memory when these instructions are performed.

5. The MCU cannot invoke these instructions while executing code from the same Flash memory for which the instruction is intended.

The MCU must operate from some other memory when these instructions are executed.

6. Writing to OTP Row is allowed only when SDP mode is disabled.
