MSP430FR6972: UCA0CLK

Part Number: MSP430FR6972

Hello,

While looking MSP430FR6972 code examples, i noticed that P1.5 was assigned as UCA0CLK. However, P2.2 can be assigned according to datasheet.

P1SEL1 |= BIT5; // USCI_A0 operation
P2SEL0 |= BIT0 | BIT1; // USCI_A0 operation

Is there any special reason for that? Can we use P2.2 too?

Thanks.
