3.8  Clock oscillator Y2

When you select the EM option on jumper W4 (jumper on pins 1-2), the clock 
signal generated by Y2 is supplied to the external inputs of the MCU. You can 
replace Y2 with another compatible clock oscillator to provide a different clock 
frequency (see schematic page 6).

3.9  EM Board Socket Connectors P1 and P2

Connectors P1 and P2 connect the EML08EY to the platform board. 
Figure 3-7 and Table 3-7 give pin assignments and signal descriptions for 
connector P1. Figure 3-8 and Table 3-8 give pin assignments and signal 
descriptions for connector P2.
