Hi,
I have one question regarding the PWM output frequency of AM437x.
Is the PWMSS module possible to output 2kHz frequency.
My customer supply 24MHz to AM4376 now.
According to Figure 6-8 Internal Clocking Architecture, CLKOUTM4/2 is used for L4 peripheral (PWMSS). It is 100MHz.
Also I can confirm it from Table 20-3 PWMSS Clock Signals of TRM. This means that CLK pulse for counter is 10ns.
Time-base Counter (TBCNT) is 16 bit counter. Clock pulse of 2kHz is 500us.
500us / 10ns = 50000
TBCNT can count from 0 to 65535. So PWMSS module can output 2KHz pulse.
Is my understanding right? Please advise me.
I appreciate your quick reply.
Best regards,
Michi
