Figure 24.13 Synchronous Data Polling Timing/Toggle Bit Timings
Notes
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 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.
Figure 24.14 Sector Protect/Unprotect Timing Diagram
Note
* Valid address for sector protect: A[7:0] = 3Ah. Valid address for sector unprotect: A[7:0] = 3Ah.
** Command for sector protect is 68h. Command for sector unprotect is 60h.
*** Command for sector protect verify is 48h. Command for sector unprotect verify is 40h.
