Disables operation with external event count input.
(Performs counting with the count clock selected by the
TAAmCTL0.TAAmCK0 to TAAmCK2 bits.)

Count clock selection
The TAAmEEE bit selects whether counting is performed with the internal count
clock or the valid edge of the external event count input.

Enables operation with external event count input.
(Performs counting at every valid edge of the external event count input
signal.)
Cautions 1. External event count input is selected in the external event count mode
regardless of the value of the TAAmEEE bit.
2. Set the TAAmEEE and TAAmMD2 to TAAmMD0 bits when the
TAAmCTL0.TAAmCE bit = 0. (The same value can be written when the
TAAmCE bit = 1.) The operation is not guaranteed when rewriting is
performed with the TAAmCE bit = 1. If rewriting was mistakenly
performed, clear the TAAnCE bit to 0 and then set the bits again (m = 0 to
3, 5).
