 The partitions for ACTIVE (+BOOTLOADER), DFU and BOOTLOADER_STATE may be placed in separate flash. The page size used by the bootloader is determined by the lowest common multiple of the ACTIVE and DFU page sizes.
-The BOOTLOADER_STATE partition must be big enough to store one word per page in the ACTIVE and DFU partitions combined.
+The BOOTLOADER_STATE partition must be big enough to store two words, plus four words per page in the ACTIVE partition.
 The bootloader has a platform-agnostic part, which implements the power fail safe swapping algorithm given the boundaries set by the partitions. The platform-specific part is a minimal shim that provides additional functionality such as watchdogs or supporting the nRF52 softdevice.
