Pulse Width Modulator (PWM8B8C)
Register Descriptions
NOTE:
Reads of this register return the most recent value written. Reads do not
necessarily return the value of the currently active period due to the
double buffering scheme.
Reference PWM Period and Duty for more information.
To calculate the output period, take the selected clock source period for
the channel of interest (A, B, SA, or SB) and multiply it by the value in
the period register for that channel:
• Left Aligned Output (CAEx=0)
PWMx Period = Channel Clock Period * PWMPERx
• Center Aligned Output (CAEx=1)
PWMx Period = Channel Clock Period * (2 * PWMPERx)
For Boundary Case programming values, please refer to PWM
Boundary Cases.
