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:
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 LPC2917/19 contains an external Static Memory Controller (SMC) which provides an
interface for external (off-chip) memory devices.
