How to decide MPC5744P PLL0 PHI0 output frequenccy?

[liwuquan]

NXP Expert,

I need help to decide how much the MPC5744P PLL0 PHI0 output frequency is.

From the above C code(mc_mode_init() in sys.c) from MTRCKTSPS5744P example code you posted, it is telling the PLL0 PHI0 output is 160HZ, its input has been selected using XOSC(the output is 8-40mhz),

where  I can find how and why the PLL PHI0 out is set at 160HZ?

question 2: how much and how in this  C motor application the system clock is set at?

Thank you.

Hi Susan,

It is good to hear you found the answer, please notice that the MCUXpresso Config Tools supports Cortex-M Kinetis and LPC devices. MPC devices are not supported.
 
I'd recommend to submit your questions to the MPC related community in the future:
