Timer_A Timer Block
The 16-bit timer (TAR) can count up to a threshold and then roll over to
zero or start counting back down to 0.
Refer to the Timer_A section of the MSP430x2xx Family User Guide for
exhaustive details on the Timer_A block.
Input Capture/Output Compare blocks (channels) are part of the
Timer_A block. These allow us to extend the use of the basic timer
block by involving input and output pins. We’ll discuss this after exam 2.
The specific interrupt vectors and input/output pins involved are
device-specific and, hence, can be found in the device-specific
datasheets.
All capture/compare blocks share a common timer block (only one
TAR).
