MSP430FR4133: Is there a minimal SBW implementation in C to flash MCP430 serie from other MCU?

Part Number: MSP430FR4133

Everything is in the title, i use an MSP430 in a design where i routed the SBW interface to the main MCU, in the perspective of remote firmware upgrade.

I would like to implement this now and i wonder if there is some existing implementations, the smaller the better, all i need is to flash the firmware, no fancy option bits to set or anything.

I can imagine there is probably a 15K lines implementation of the MSP FET or something in some DLL, but i am looking for something more reasonnable, i have done that in the past for differnt MCU / SOC (ST, Cypress, Atmel) and it can be done in few thousand laines or less with SWD.

Thank you.
