p: Setting value of the DTT register, 01h to FFh
fi: Count source frequency (f1TIMAB, f2TIMAB, f1TIMAB divided by 2,
f2TIMAB divided by 2)
Selectable either active high or active low
Simultaneous conduction prevention
Simultaneous conduction detection
A timer B2 interrupt is generated every carrier wave cycle to every 15 carrier
wave cycles.
