CHAPTER 9 16-BIT TIMER/EVENT COUNTER T (TMT)
9.6.3 External trigger pulse output mode (TT0MD3 to TT0MD0 bits = 0010)
In the external trigger pulse output mode, 16-bit timer/event counter T waits for a trigger when the TT0CTL0.TT0CE bit
is set to 1. When the valid edge of an external trigger input (TENC00) is detected, 16-bit timer/event counter T starts
counting, and outputs a PWM waveform from the TOT01 pin.
Pulses can also be output by generating a software trigger instead of using the external trigger. When using a software
trigger, a square wave that has the set value of the TT0CCR0 register + 1 as half its cycle can also be output from the
TOT00 pin.

Notes 1. The external trigger input (TENC00) pin is also used for the external event count input function.
In the external trigger pulse output mode, therefore, the external event count input function
cannot be used.
2. Edge detector for external trigger input.
Set by the TT0IOC2.TT0ETS1 and TT0IOC2.TT0ETS0 bits.
3. Edge detector for external event count input.
Set by the TT0IOC2.TT0EES1 and TT0IOC2.TT0EES0 bits.
