25 / 95 page  September 10, 2007 S29GL-A_00_A11 S29GL-A 25 Data She e t 7.6 RESET#: Hardware Reset Pin The RESET# pin provides a hardware method of resetting the device to reading array data. When the RESET# pin is driven low for at least a period of tRP, the device immediately terminates any operation in progress, tristates all output pins, and ignores all read/write commands for the duration of the RESET# pulse. The device also resets the internal state machine to reading array data. The operation that was interrupted should be reinitiated once the device is ready to accept another command sequence, to ensure data integrity. Current is reduced for the duration of the RESET# pulse. When RESET# is held at VSS±0.3 V, the device draws CMOS standby current (ICC5). If RESET# is held at VIL but not within VSS±0.3 V, the standby current is greater. The RESET# pin may be tied to the system reset circuitry. A system reset would thus also reset the Flash memory, enabling the system to read the boot-up firmware from the Flash memory. Refer to the tables in AC Characteristics on page 72 for RESET# parameters and to Figure 16.4 on page 75 for the timing diagram. 7.7 Output Disable Mode When the OE# input is at VIH, output from the device is disabled. The output pins are placed in the high impedance state.
