Actually it's quite common when we have several HW blocks of the
same thing to add something like an id. For example for different
GPIO banks.

But in this case I guess it may make more sense to flag one MSP
for RX and one for TX or something?

There are also two more such MSPs for streaming audio to the
Bluetooth audio portions.
