9.1.1.9.2 Reset Instruction – PSD913F2
The Reset instruction consists of one write cycle (see Table 9). It can also be optionally
preceded by the standard two write decoding cycles (writing AAh to 555h and 55h to
AAAh).
The Reset instruction must be executed after:
1. Reading the Flash Protection status or Flash ID
2. When an error condition occurs (DQ5 goes high) during a Flash programming or erase
cycle.
The Reset instruction will reset the Flash to normal Read Mode. It may take the Flash
memory up to few msec to complete the reset cycle.
The Reset instruction is ignored when it is issued during a Flash programming or Bulk
Erase cycle. During Sector Erase cycle, the Reset instruction will abort the on going sector
erase cycle and return the Flash to normal Read Mode in up to few msec.
9.1.1.9.3 Reset Instruction – PSD934F2, PSD954F2
The Reset instruction consists of one write cycle (see Table 9). It can also be optionally
preceded by the standard two write decoding cycles (writing AAh to 555h and 55h to
AAAh).
The Reset instruction must be executed after:
1. Reading the Flash Protection status or Flash ID
2. When an error condition occurs (DQ5 goes high) during a Flash programming or erase
cycle.
The Reset instruction will immediately reset the Flash to normal Read Mode. However,
if there is an error condition (DQ5 goes high), the Flash memory will return to the Read
Mode in 25 sec 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 sec.
