[MSP430F2272] USCI30

Other Parts Discussed in Thread: MSP430F2252

I received the next information from TIJ FAE.

For the USCI30

Correct and the MSP430F2252 does not come with a DMA so that will be the only option. But in the case that the receive buffer
cannot be read out in time, you could do this:

Q1: Can this work around also fit reception of a slave mode?

Q2: If we were using the I2C clock stretch, whether this UCI30 does not occur?

                  ^^^^^^^^ -> clock stretch
