ARM9 microcontroller with CAN and LIN

Table 10 gives an overview of the ﬂash-sector base addresses.

Availability of sector 15 to sector 18 depends on device type, see Section 3 “Ordering information”.

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.

6.8.5 Flash bridge wait-states

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:

(1)

Asynchronous reading:
