10.4.6 Interrupt Timing
The interrupt timing is illustrated in Figure 29, and described in Table 24.
67
IRQ#
1. Specified from the final positive crossing of Vcc above 2.7V.
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.
