The maximum amount of addressable memory by a single asynchronous memory bank is 2MByte. In order to be
able to use more than 2MByte on a single bank 2 GPIOs are used to select which 2MB section of flash is active in the
memory window of the Blackfin processor. This frees up the remaining banks for the user.
The maximum amount of memory addressable by the processor is 8MByte.
*) PF5 is routed by default to the connector of the Core Module. Nevertheless this pin can be used to select bank2/3
of the flash memory. To realize this, the 0Ω resistor R18 must be removed and a 0Ω resistor R19 must be soldered to
the Core Module. In this case PF5 is routed to the flash memory instead to the connector!
