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?
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:
Hope it helps!
