25.1 Introduction
The FTMRG32K1 module implements the following:
• 32Kbytes of P-Flash (Program Flash) memory
• 1 Kbytes of EEPROM memory
The Flash memory is ideal for single-supply applications allowing for field reprogramming without
requiring external high voltage sources for program or erase operations. The Flash module includes a
memory controller that executes commands to modify Flash memory contents. The user interface to the
memory controller consists of the indexed Flash Common Command Object (FCCOB) register which is
written to with the command, global address, data, and any required command parameters. The memory
controller must complete the execution of a command before the FCCOB register can be written to with a
new command.
CAUTION
A Flash word or phrase must be in the erased state before being
programmed. Cumulative programming of bits within a Flash word or
phrase is not allowed.
