MSP430FR5969: TLV -reprogrammable or one time only?

Rich McNeil

Part Number: MSP430FR5969

Hi,

I see that the TLV data referenced is read only to the user. Is it possible that this data can be reprogrammed at the factory or is it truly one time only programming?

thank you.

Hello,

Good question. In the MSP430FR5969, the TLV is stored in FRAM but with not write access to it. So it's read only memory. https://e2e.ti.com/support/microcontrollers/msp-low-power-microcontrollers-group/msp430/f/msp-low-power-microcontroller-forum/710101/msp430fr5969-device-descriptor-tlv-user-perrmission
