I am looking at the CE218472 example. How do I find out what the Internal VREF is? In the pdf, it gives a 400mv Range. Vref (0.4V ~ 0.8V.] Is there a way to select what the internal Vref is? Is this really the range and and it can trigger anywhere between 0.4 and 0.8V?
Secondly, is there a way to do a software reset? I want to do it in the LPC ISR. I saw that there is a Cy_SysLib_SoftResetCM4(), but that is just the CM4 core and it has to be in deep sleep. I want an external voltage to generate a soft reset for both cores. Is that possible?
The internal voltage reference connected to negative input terminal of LPComp is not a precision reference and can vary from 0.4 V–0.8 V.
System reset could be done by using CMSIS NVIC_SystemReset() function. It resets both CM0P and CM4 cores.
