ARM9 microcontroller with CAN and LIN
Both buffer lines are invalidated after:
Initialization
Configuration-register access
Data-latch reading
Index-sector reading
The modes of operation are listed in

Flash memory controller pin description
The flash memory controller has no external pins. However, the flash can be programmed
via the JTAG pins, see
Section 7.1.3
.
8.1.4
Flash memory controller clock description
The flash memory controller is clocked by CLK_SYS_FMC, see
Section 7.2.2
.
8.1.5
Flash layout
The ARM processor can program the flash for ISP (In-System Programming) and IAP (In-
Application Programming). Note that the flash always has to be programmed by ‘flash
words’ of 128 bits (four 32-bit AHB bus words, hence 16 bytes).
The flash memory is organized into eight ‘small’ sectors of 8 kB each and up to 11 ‘large’
sectors of 64 kB each. The number of large sectors depends on the device type. A sector
must be erased before data can be written to it. The flash memory also has sector-wise
protection. Writing occurs per page which consists of 4096 bits (32 flash words). A small
sector contains 16 pages; a large sector contains 128 pages.
Table 9
gives an overview of the flash-sector base addresses.

Flash read modes
for single (non-linear) reads; one flash-word read per word read
default mode of operation; most recently read flash word is kept until
another flash word is required
Asynchronous timing
No buffer line
Single buffer line
one flash-word read per word read
most recently read flash word is kept until another flash word is
required
on a buffer miss a flash read is done, followed by at most one
speculative read; optimized for execution of code with small loops
(less than eight words) from flash
most recently used flash word is copied into second buffer line; next
flash-word read is started; highest performance for linear reads
Dual buffer line, single
speculative
Dual buffer line, always
speculative
