The TOGGLE_HI mode enables control of the timing of both the asserting
and deasserting edges of the output waveform produced. The phase
between the asserting edges of two timer outputs is programmable. The
effective state of the PULSE_HI bit alternates every period. The adjacent
active low and active high pulses, taken together, create two halves of a
fully arbitrary rectangular waveform. The effective waveform is still active
high when PULSE_HI is set and active low when PULSE_HI is cleared. The
value of TOGGLE_HI has no effect unless the mode is PWM_OUT and
PERIOD_CNT = 1.
In TOGGLE_HI mode, when PULSE_HI is set, an active low pulse is generated
in the first, third, and all odd-numbered periods, and an active high pulse
is generated in the second, fourth, and all even-numbered periods. When
PULSE_HI is cleared, an active high pulse is generated in the first, third,
and all odd-numbered periods, and an active low pulse is generated in the
second, fourth, and all even-numbered periods.
这是手册上的一段，我也没看懂，请问这是实现同频时钟的不同相位吗？
