13.3.2/13-432 - Add caution concerning register writes while command is active
13.3.2.1/13-433 - Writes to FCLKDIV are allowed during reset sequence while CCIF is clear
13.4.3.2/13-451 - Add caution concerning register writes while command is active
13.6/13-472
- Writes to FCCOBIX, FCCOBHI, FCCOBLO registers are ignored during
reset sequence
13.1 Introduction
The FTMRC128K1 module implements the following:
•
•
128 Kbytes of P-Flash (Program Flash) memory
4 Kbytes of D-Flash (Data Flash) 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.
