9.1.1.9.2 Reset Instruction
The Reset instruction consists of one write cycle (see Table 8). It can also be optionally
preceded by the standard two write decoding cycles (writing AAh to AAAh and 55h to
554h).
The Reset instruction must be executed after:
1. Reading the Flash Protection status or Flash ID using the Flash instruction.
2. When an error condition occurs (DQ5 (DQ13) goes high) during a Flash programming
or erase cycle.
The Reset instruction will reset the Flash to normal Read Mode immediately. However, if
there is an error condition (DQ5 (DQ13) goes high), the Flash memory will return to the
Read Mode in 25 μSeconds after the Reset instruction is issued.
The Reset instruction is ignored when it is issued during a Flash programming or Bulk
Erase cycle. The Reset instruction will abort the on going sector erase cycle and return the
Flash memory to normal Read Mode in 25 μSeconds.
9.1.1.9.3 Reset Pin Input
The reset pulse input from the pin will abort any operation in progress and reset the Flash
memory to Read Mode. When the reset occurs during a programming or erase cycle, the
Flash memory will take up to 25 μSeconds to return to Read Mode. It is recommended that
the reset pulse (except power on reset, see Reset Section) be at least 25 μSeconds such
that the Flash memory will always be ready for the MCU to fetch the boot code after reset
is over.
