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 MSP432 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.
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).
