26.1 Introduction
The FTM384K2 module implements the following:
• 384 Kbytes of P-Flash (Program Flash) memory, consisting of 2 physical Flash blocks, intended
primarily for nonvolatile code storage
• 32 Kbytes of D-Flash (Data Flash) memory, consisting of 1 physical Flash block, that can be used
as nonvolatile storage to support the built-in hardware scheme for emulated EEPROM, as basic
Flash memory primarily intended for nonvolatile data storage, or as a combination of both
