6.4.2 Configuring the Dual Partition

In the Dual Partition modes, two independent applications may be programmed into the device, one to each of two Flash memory partitions, known as Partition 1 and Partition 2. When the device is initialized, one of these is dynamically mapped to the active partition and executed. The other is mapped to the inactive partition, where it remains available to program memory operations. The assignment of a partition to the active or inactive partition is determined automatically by a code signature, known as the Boot Sequence Number (BTSEQn). The code partitions may also be swapped between active and inactive partitions during run time under software control.
