CHAPTER 8 16-BIT RELOAD TIMER
■ Output Terminal Functions
TOT1 and TOT2 output terminals perform as a toggle output inverting by underflows when reload mode,
and as a pulse output indicating the counting process when one-shot mode. Output polarity can be set by
OUTL bit of the register. When OUTL=0, an initial value of the toggle output is "0", and one-shot pulse
output outputs "1" while counting. When setting OUTL=1, output waveform is inverted.
