Timer_A
Timer_A
This section describes the basic functions of the MSP430 general-purpose
16-bit Timer_A. All capture/compare blocks (CCR) are identical.
MSP430x11x, MSP430x11x1, and MSP430x13x have three CCRs
(Timer_A3) and MSP430x14x has five CCRs (Timer_A5) implemented.
Note:
Throughout this chapter, the word count is used in the text. As used in these
instances, it refers to the literal act of counting. It means that the counter must
be in the process of counting for the action to take place. If a particular value
is directly written to the counter, then the associated action will not take place.
For example, the CCR0 interrupt flag is set when the timer
counts up to the
value in CCR0. The counter must count from CCR0–1 to CCR0. If the CCR0
value were simply written directly to the timer with software, the interrupt flag
would
not be set, even though the values in the timer and the CCR0 registers
are the same.
