NOTES: 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 array mode if DQ5 goes high or after
reading the Flash Identifier or Protection 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.
