Table 9. Instructions

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.
