The SG family does not have a clock out pin, if you want to get the 32KHz from the internal clock this is not possible, but you can use the internal FLL and the TPM module to get a PWM signal on one of the TPM channels, I  do not remember if this possible to have 32KHz using the TPM, please check the following code, this is for the SH, the SH has the same modules than the SG

You only can have a PWM signal (square signal), not a clock signal (sine signal)

 

Have a good day
