10.4.6 Interrupt Timing
The interrupt timing is illustrated in Figure 25, and described in Table 23.
63
IRQ#
1. Specified from the final positive crossing of Vcc above 2.5V and VCCQ above 1.65 or 2.5V.
2. If the assertion of RSTIN# occurs during a flash erase cycle, this time could be extended by up to 500 µS.
3. Normal read/write cycle timing applies. This parameter applies only when the cycle is extended until the negation of the BUSY#
signal.
4. Applies to multiplexed interface only.
5. When operating DiskOnChip with separate power supplies for VCC and VCCQ, it is recommended to turn both power supplies
on and off simultaneously. Providing power separately (either at power-on or power-off) can cause excessive power dissipation.
Damage to the device may result if this condition persists for more than 1 second.
