I have a beginner question on how pins for peripherals are displayed on the datasheet. I'm looking at the datasheet for MSP430FR6989
Datasheet states clearly there are 2 eUSCI A peripherals and 2 eUSCI B peripherals. I am concerned with the UCAx perhiperals. There appear to be multiple pins on the package that are named the same for the same eUSCI peripheral bus.
For example: UCA0RXD is shown on pin 50 .... but UCA0RXD is also shown on pin 1 on the package.
UCA0TXD is shown on pin 51 ... but also shown on pin 100
UCA1RXD/TXD is the same: shown on pins 40/41 but also on pins 87/88
So if I wanted to use UCA0RXD/TXD .... do I use pins 1/100 or pins 50/51? How do I select which pins I want to use? I understand how to configure a GPIO for a specific function but I don't understand why the same peripheral ports appear on more than one pin.
