Question
How many of the USCI channels can be used at the same time?
Answer
Each USCI has 2 serial channels (1 "A" Channel, 1 "B" Channel) which can be run at the same time or independently. Each channel is mutually exclusive of the other.
Care needs to be taken that the required configuration is available on the pinout of the MSP430. This can be determined by looking at the pin description in the device datasheet. Multiplexing of the MSP430 pins can prevent some configurations from being used.
For devices with 2 USCI modules, then four channels are available: two "A" Channels and two "B" Channels. These are all independent and can be run simultaneously as long as the pinout for that device permits access to all necessary configurations.
