The device specific data sheet SLAS735J for my launchpad MSP430G2x53 lists in Table 20 = 'Port P2 (P2.0 to P2.5) Pin Functions', some nomenclature that I am having trouble understanding, leading to these 3 questions:
What is meant by Timer1_A3.CCI1A? I know Timer1_A3 just means Timer 1. But what does .CCI1A stand for?
This table defines the pin assignments as functions of the P2DIR and P2SEL bits. For the P2.1 and P2.2 pins, with P2DIR.1,2 =0, I understand that these pins are set as inputs. But with P2SEL.1,2 = 0, for instance, Pin P2.1 is assigned = Timer1_A3.CCI1A and Pin P2.2 is assigned = Timer1_A3.CCI1B. What is meant by A and B?
Is there an app note that gives more detail on the basic nomenclature?
