Timer Unit

this counter, it can generate three types of timer interrupts (INTTMR1 to 3). These timer interrupts may be used to
produce a commutation trigger, position detection start trigger, etc. Also, the mode timer has a capture function which
automatically captures register data in synchronism with position detection or overload protection. This capture func-
tion allows motor revolutions to be calculated by measuring position detection intervals.
fc/4
The timer unit has an up counter (mode timer) which is cleared by a position detection interrupt (INTPDC). Using
