    PSoC4S CY8C4126AXI-S445 EXTCLK settings




      In order to operate PSoC4S with an external clock,
      Enabled EXTCLK of Configure System Clocks.


      Frequency is 24MHz
      Accuracy is -2% to + 2%.

      HFCLK set to EXTCKL


      No error occurs after Build.

      The clock of the SG-8002CE24MHSTB-L3 oscillator is input to P0 [6].


      However, PSoC4 does not start after programming.
      Are there any restrictions on how to use an external clock?

      For example, are there any application notes listed?
