MSP430FR2153: BSL Resources Used? UART MSP430FR2153

Intellectual 450 points
Part Number: MSP430FR2153

I'm reading SLAU319AD REVISED JUNE 2020 
which lists the pins for the BSL for each MSP430 part.
However there's no listing in the resource table for "FR215x" series parts.
The master table shows UART or I2C support, but no pin numbers.

    Am I correct that the bootloader does not use UCA0 nor UCA1, but rather two random I/O ports?

    The MSP430FR2153 datasheet SLASEC4D has:

    Where:

    • The UART BSL pins are for UCA0TXD / UCA0RXD
    • The I2C BSL pins are for UCB0SDA / UCB0SCL

    Does this answer your question?
