29.2.1.1 Code flash
Partition 0 accounts for 1.5 MB of the total Flash Memory and is divided in 6 user blocks for
code storage. The first 256 KB blocks are organized as 1 × 256 KB. Remaining blocks are
256 KB.
Partition 0 also contains a reserved block named TestFlash in which some One Time
Programmable (OTP) user data is stored.
The sectorization of partition 0 of the 1584 KB Flash Memory module is shown in
