Primary peripheral clock frequency on the ARM Cortex-R processors

Model Configuration Pane: Hardware Implementation / Simulink or Embedded Coder Hardware Support Package / Hardware board settings / Target hardware resources / Clocking


The Primary Peripheral Clock Frequency (MHz) parameter indicates the frequency of the primary peripheral clock (VCLK).


The primary peripheral clock frequency is automatically determined and set from the CPU Clock Frequency (MHz).


75 (default) | 110
