(1) Each number in the sequence represents an instantiation of Timer_A with its associated number of capture/compare registers and PWM output generators available. For example, a number sequence of 3, 5 would represent two instantiations of Timer_A, the first instantiation having 3 capture/compare registers and PWM output generators and the second instantiation having 5 capture/compare registers and PWM output generators, respectively.
(2) Each number in the sequence represents an instantiation of Timer_B with its associated number of capture/compare registers and PWM output generators available. For example, a number sequence of 3, 5 would represent two instantiations of Timer_B, the first instantiation having 3 capture/compare registers and PWM output generators and the second instantiation having 5 capture/compare registers and PWM output generators, respectively.
(3) eUSCI_A supports UART with automatic baud-rate detection, IrDA encode and decode, and SPI.
(4) eUSCI_B supports I2C with multiple slave addresses, and SPI.
(5) Timers TA0 and TA1 provide internal and external capture/compare inputs and internal and external PWM outputs.
(6) Timers TA2 and TA3 provide only internal capture/compare inputs and only internal PWM outputs (if any).
