Part Number: MSPM0L2117
The MSPM0L2117 appears to use UNICOMM devices for I2C/SPI/UART serial ports [Ref datasheet (SLASFN5) Sec 8.23], but I don't see a section describing UNICOMM in the latest TRM (SLAU847E). (I admit that the similarities with the "old" I2C/UART/SPI are evident.)
I suppose there's a new rev of the TRM coming soon, but in the meantime will I succeed if I refer to the relevant chapters from the MSPM33C3 TRM (SLAU962)?
