The CNTRSEL bit in the UCON register selects whether P1_7 can be used as the CNTR00/INT10
input pin or P1_5 can be used as the CNTR01/INT11 input pin.
When the CNTRSEL bit is set to “0”, P1_7 is used as the CNTR00/INT10 pin and when the
CNTRSEL bit is set to “1”, P1_5 is used as the CNTR01/INT11 pin.
