6.8.3 Flash bridge wait-states
6.8.4 Pin description
6.8.5 Clock description
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, once programmed, cannot be erased. Any flash operation must
be executed out of SRAM (internal or external).
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:
Synchronous reading:
Asynchronous reading:
Remark: If the programmed number of wait-states is more than three, flash-data reading
cannot be performed at full speed (i.e. with zero wait-states at the AHB bus) if speculative
reading is active.
The flash memory controller has no external pins. However, the flash can be programmed
via the JTAG pins, see
The flash memory controller is clocked by CLK_SYS_FMC, see
