System Crystals

Two different crystal oscillator inputs are available on the board. The WCO kHz crystal (32.768 kHz)
is populated and is used for timing. A footprint for the ECO MHz crystal and load capacitors are on
the board so that you can easily select the crystal of your choice. The ECO is optional and only
required when the internal clock must be more accurate than the internal main oscillator (IMO). The
internal FLL and PLL help to provide a wide range of options with either the ECO or IMO.

10-pin SWD/JTAG Programming Header

The board has a provision for the 10-pin header J9, which allows you to program and debug the
PSoC 64 device using an external programmer such as MiniProg4. This is not loaded by default.
