Product data sheet
6.8.5 Flash bridge wait-states
Table 10
Table 10.

The index sector is a special sector in which the JTAG access protection and sector
security are located. The address space becomes visible by setting the FS_ISS bit and
overlaps the regular flash sector’s address space.
Note that the index sector cannot be erased, and that access to it has to be performed via
code outside the flash.
To eliminate the delay associated with synchronizing flash-read data, a predefined
number of wait-states must be programmed. These depend on flash-memory response
time and system clock period. The minimum wait-states value can be calculated with the
following formulas:
