Problem with 4-SMD Crystal / PIC16F1575
From Microchip:


  The External Clock (EC) mode allows an externally
  generated logic level signal to be the system clock
  source. When operating in this mode, an external clock
  source is connected to the CLKIN input. CLKOUT is
  available for general purpose I/O or CLKOUT.
  Figure 5-2 shows the pin connections for EC mode




This chip is not designed with an internal clock source from an RC oscillator.  But it has no oscillator to run a crystal.  If you want an external 32MHz clock source, you need to generate it and then apply it to the chip.
