Hello
I have a question regarding the power management section of the S32K314 MCU.
[Figure1]
In [Figure 1], it appears that VRC_CTRL is the signal responsible for determining whether to supply 1.5V to the internal core. My question is, does VRC_CTRL enter the BASE through GPIO, or is it input as a different waveform?
Thank you for your help!
Hi @malove ,
No, it is an analog signal which controls base of external BJT, as it is depicted on your picture.
Best regards,
Pavel
Thank you @PavelL
If I am using VRC_CTRL, is the output of VRC_CTRL PWM?
Hi @malove ,
if VRC_CTRL is not used (please refer to S32K3XXRM rev9 chapter 42.7.3 PMC Configuration Register (CONFIG), bits LMBCTLEN and LMEM), the pin can be used as PTE13.
Best regards,
Pavel
