Note: 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.

1. The timings are similar to synchronous read timings and asynchronous data polling Timings/Toggle bit Timing.
2. VA = Valid Address. Two read cycles are required to determine status. When the Embedded Algorithm operation is complete,
the toggle bits will stop toggling.
3. 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.
4. Data polling requires burst access time delay.
