F29H85X-SOM-EVM: Consultation on Chip Peripheral Status

Li Geng

Tool/software:

At present, I've only found a module named CPU Timer in the manual. However, it doesn't meet my requirements. My requirements are as follows:

The timer counts upwards.
It has a compare value register which loads a compare value. When the count value reaches this compare value, an interrupt is generated. At this time, the counter does not clear automatically but continues to count upwards until it overflows and restarts counting from the beginning.

Is there such a timer in the chip?

Hi Li,

We only have the one type of CPU timer on this device. However, the event generation submodule of the EPWM can do this.

Best Regards,

Hi Li,

PWM has its counter, which can be configured in up count mode and has compare values (CMPA,CMPB,CMPC etc) registers and the following submodule in EPWM peripheral can generate interrupt when counter == CMPA and keep on counting up and reset when equals TBPRD (the overflow period value set by user) and count from zero again.

Please refer to the above section

Thanks
