MSP430FR5969-SP: MSP430FR5969 SPY Bi-Wire to configure MSP

Hi,

I noticed in the datasheet, it mentions that SPY Bi-Wire can be used to interface with MSP430 development tools and device programmers.

Does this prevent me from using this on my board without these devices? In other words I have an ARM processor that will be used to configure this device.

I have a couple of ways to do this:

1) BSL over UART interface and then once configured use this as a standard UART interface for reading and writing

2) Use the SPY Bi-wire interface to configure the device and use the UART interface for reading and writing

Would there be any reason why either of these options won't work or is the SPY Bi-wire just intended for development tools and programmers?

Thanks!
