MSP430FR5969: Custom BSL on FRAM

Part Number: MSP430FR5969

Hello,

I have made a controller based on 'FR5969 and now we need to be able to make remote updates using UART. The problem is that my controller uses a RS-485 converter attached to the UART from eUSCI0 and microcontroller itself is responsible, through a GPIO, to control the TX/RX switch of the converter. Since BSL communication is bidirectional, I still need to have control of this GPIO pin in order to establish bidirectional communication. Only a custom BSL would do the trick.

I have seen that 5xx and 6xx families are able to have a custom BSL, but only found examples for older, Flash EEPROM models. Is it OK to use the same addresses and definitions for FRAM models like FR5969? 

Thanks in advance for your help,

Mario
