The flash memory is subdivided into addressable banks with 2 MByte size.
The pin-connections for FA22-FA24 can be customized. Please contact Bluetechnix Support for more information.
*⁾ Be aware that you have to unlock the flash before starting an erase process!
**) Only valid if 64 MByte flash mounted (see chapter 8 Production Report)
2.3.1 Asynchronous Memory Banks
The maximum amount of memory addressable by a single asynchronous memory bank, of the Blackfin processor is
1MB. On this module, each 2MB segment of Flash is addressed over 2 asynchronous memory banks. In order to be
able to use more than 2MB without using more than 2 banks, 2 GPIOs (PF4, PF5) are used to select which 2MB
section of the FLASH is visible in the memory window of the Blackfin processor. This frees up the remaining banks
for the user.
Aside from the first 2 async memory banks, which are used for FLASH addressing, the core module has 2 banks of
the Asynchronous Memory interface available, these can be addressed through the following addresses:

Table 2-3: Asynchronous memory banks
These memory banks can be used to access various memory mapped devices or peripherals.
*There are 19 address lines (A1 to A19) (The A0 signal is produced through addressing logic on ABE0 and ABE1), this
allows the entire 1MB to be addressable bytewise.
See section 5.6, Flash Memory Extension PINS.
