Hi,
I am building a master-slave system using F28035 MCUs. The plan is to use the master MCU's ePWM signal to clock the slaves' CPU timer2. There, the whole system will have a global time.
I read the manual of F28035 and it says
CPU-Timer 2 can be clocked by any one of the following:
• SYSCLKOUT (default)
• Internal zero-pin oscillator 1 (INTOSC1)
• Internal zero-pin oscillator 2 (INTSOC2)
• External clock source
However, I don't know how exactly to externally clock CPU-timer 2. I guess I should use one of the GPIO pin to connect to an external clock signal, say, the ePWM output pin of the master MCU. And I may need to set a control register's value to make it externally clock?
I can't find more detail about this topic in the manuals, would somebody please help me with this?
If this is a sample code, that will be great!
Thanks a lot!
Alfred
