FWKEY is the password for the flash memory and should be included for every action. This article will help all of us who are struggling to use the flash memory. They are well documented on the internet. However, the trouble starts with writing data.
I would be more than happy to learn from you. A, B, C, D are 64 byte segments and the others are byte segments. Initially, I was reluctant to use the flash but had no other option. Use of the information on this site may require a license from a third party, or a license from TI. Also note that addresses 0xfexffff hold interrupt vectors.
There will be a pointer to the flash space and you just need to reference that pointer.

Hence, once a segment is erased, we can perform 4 buffer writes.

The trouble is that flash memory is not easy to handle. Please feel free to comment. This will erase the whole segment. Note that each segment is bytes and hence it can hold integers each integer in msp is 2 bytes. After configuring the registers, a dummy write must be done to the given address.
Once a segment is erased, data can be written to it. I needed to store bytes. Even if you want to store one single byte, you need to erase the whole segment.
So I started off. After that, the flash must be configured in erase mode. The flash is arranged as segments A, B, C, D and other segments. When you wish to write to a segment, you need to erase it first. Soon I realised that I needed to store a large amount of data.

But not that difficult either. This will not teach you C programming, using MSP or flash memory basics.
This will result in the microcontroller malfunctioning after restart since the interrupt vector will get erased and the microcontroller will not know where to start from. Once the erase is complete, the memory should be locked and interrupts enabled again.I am using an MSPFA in large memory model.
I have 'mspx' silicon version selected. It seems that no matter what I do, I cannot use the __data16_write_addr() function to compile without throwing the following warning. however upon compiling I am getting a waring informing me that __data16_write_addr() is being declared implicitly.
This presumably means that I'm not including a required file, however when looking at example code the only file include at the top is "msph" which I am also including.
This code will set P if RX character // is correct and clears P if received character is wrong. Watchdog in // interval mode triggers block transfer every ms. Placing Variables in Specific Memory Location - MSP From Texas Instruments Wiki.

MSP Launchpad interface with 16×2 LCD Display. Here I summarize the project of interfacing the 16×2 LCD Display with MSP Launchpad. Hardware Connection. Here we use 4-bit mode (data bus D7-D4 only) to communicate with LCD display since we don’t have sufficient Pins in MSP Launchpad for 8-bit communicaton.
I used a lot of code. Jane, you are correct. Actually running code from SRAM would make more sense for devices which has much bigger SRAM size. Anyway I decided to write it for MSPG since the MSP-EXPG2 Launchpad is the most popular kit for MSPDownload
