CHAPTER 7 16-BIT TIMER/EVENT COUNTER P (TMP)
7.5.5 PWM output mode (TP0MD2 to TP0MD0 bits = 100)
In the PWM output mode, a PWM waveform is output from the TOP01 pin when the TP0CTL0.TP0CE bit is set to 1.
In addition, a pulse with one cycle of the PWM waveform as half its cycle is output from the TOP00 pin.
