Using PWMA to output 3 sets of complementary PWM for driving MOSFEET, Using PWMB for capturing external throttle signals, Using ADC to sample voltage and current, for low voltage protection and over current protection(But I'm not done yet). Using internal OPA and BEMF to estimate rotor position. TMR0 and TMR1 is used to calculate commutation time and motor timing.TMR2 is used for the serial port. TMR3 and TMR11 are used for the delay function (in fact, only one is needed). TMR4 is used to complete some periodic tasks.
