S32K312-How to configure the CLKOUT_STANDBY function

Simon-Liu — Fri, 29 Mar 2024 07:01:38 GMT

Hello

I want to use the S32DS tool to configure the PTA12 terminal as CLKOUT_STANDBY function, what configuration is required besides configuring PTA12 as [clockout_standby] in [Pins]?
How to configure the [CLKOUT_STANDBY] bit in register DCMRWP1?

BestRegards

Simon

Hi @Simon-Liu

I am afraid that at the moment, the RTD driver does not support enabling DCMRWP1[3]. So, there is no way to configure the DCMRWP1[3] bit. So, in this situation, you must use a code register to enable this bit in your code.

Hi @VaneB

Then enable DCMRWP1[3] in the code, and configure the terminal PTA12 as the CLKOUT_STANDBY function. After entering the StandBy mode, what frequency will the PWM output of the terminal be changed?

Hi @Simon-Liu

Could you please clarify what you mean by "PWM output of the terminal be changed"?

Hi @VaneB

Sorry my description may not be clear.
My question is, when configuring terminal PTA12 as the CLKOUT_STANDBY function, after entering StandBy mode, this terminal can also output a waveform with changing high and low levels. So how to set the frequency of this output?

Hi @Simon-Liu

Please refer to Figure 58 (Clockout overview) of the S32K3xx Reference Manual, Rev. 8.
