9.2. Configure Flash and OTP wait states: Verify User Option 1 and Verify User Option 2
Verify User Option 1 and User Option 2 allows you to specify
wait states used for the Flash and OTP memory during the
verify operation. This option can be used to increase the speed
of the verify operation or allow you to match the wait states used
in your application if desired.
CAUTION:
Frequency limits for both the Flash and OTP blocks are documented in the device
Data Manual (SPRS174). Refer to the Data Manual for the minimum access time of
the Flash and OTP memory. Using a wait state value that is too low will cause the
verify operation to fail.
Verify User Option 1 specifies the Flash waitstate register (FBANKWAIT) contents:
FBANKWAIT Register
The sample SDFlash project uses the default value of 0F0F. This value is also used if the option is left blank.
