5.6 Dual Partition Flash Configuration

For dsPIC33CK512MPT608 devices operating in Dual Partition Flash Program Memory modes, the Inactive Partition can be erased and programmed without stalling the processor. The same programming algorithms are used for programming and erasing the Flash in the Inactive Partition, as described in RTSP Operation. On top of the page erase option, the entire Flash memory of the Inactive Partition can be erased by configuring the NVMOP[3:0] bits in the NVMCON register.

Note: The application software to be loaded into the Inactive Partition will have the address of the Active Partition. The bootloader firmware will need to offset the address by 0x400000 in order to write to the Inactive Partition.
