Hi @mogilipuri_harish
eMIOS is clocked by CORE_CLK(up to 160Mhz). eMIOS divides this clock by the global prescaler (MCR[GPRE] + 1) and routes the resulting prescaled clock output to the channel internal prescaler (Cn[UCPRE] + 1). Thus channel internal counter counts (CORE_CLK/global prescaler/internal prescaler) clock.
For example if the channel is running in OPWFMB mode, its PWM frequency is calculated as:
PWM frequency = CORE_CLK / global prescaler / internal prescaler / (B1+1)
Where B1 is the value of the B register.
Please refer to device RM for description of eMIOS modes.
