Figure 29. Toggle Bit Timings (During Embedded Algorithms)
Note
73.VA = Valid address; not required for DQ6. Illustration shows first two status cycle after command sequence, last status read cycle, and array data read cycle.
Figure 30. DQ2 vs. DQ6 for Erase/Erase Suspend Operations
Note
74.The system may use CE# or OE# to toggle DQ2 and DQ6. DQ2 toggles only when read at an address within an erase-suspended sector.
Figure 31. Synchronous Data Polling Timing/Toggle Bit Timings
Notes
75. The timings are similar to synchronous read timings and asynchronous data polling Timings/Toggle bit Timing.
76. VA = Valid Address. Two read cycles are required to determine status. When the Embedded Algorithm operation is complete, the toggle bits will stop toggling.
77. RDY is active with data (A18 = 0 in the Configuration Register). When A18 = 1 in the Configuration Register, RDY is active one clock cycle before data.
78. Data polling requires burst access time delay.
