Memory Map
The C3 Discrete device is asymmetrically blocked, which enables system code and data
integration within a single flash device. The bulk of the array is divided into 32 Kword
main blocks that can store code or data, and 4 Kword boot blocks to facilitate storage
of boot code or for frequently changing small parameters. See
