Flash Memory
This chapter describes the MSP430 flash memory module. The flash memory
module is electrically erasable and programmable. Devices with a flash
memory module are multiple-time programmable devices (MTP). They can be
erased and programmed off-board, or in a system via the MSP430’s JTAG pe-
ripheral module or via the processor’s resources.
Software running on an MSP430 device can erase and program the flash
memory module. This active software may run in RAM, in ROM, or in the flash
memory. The flash memory may be a different memory module or the same
memory module. The active software may not be in a memory location which
is actively erased.
