    Default Any chances for HPWM to generate 50Hz output?

    Hello.
    As PBP manual says, there are some limitations for HPWM lowest frequency.
    Are these PBP limitations or hardware limitations?
    I want to have two 50% duty cycle, 50Hz pulses generated with dead time, using built in hardware PWM module (16/18 series midrange)
    Is this possible?

    yes a PIC16F18446 or similarly equipped chip @fosc=4MHz can do that by combining the PWM module output with the CWG module.
    unfortunately fosc/4 is the only acceptable clock source for pwm generation for 8 bit pic's so options are limited a bit for overall accuracy and dead time resolution.
