3.3.3 How to mount oscillator on MCU board

Plug crystal oscillator or ceramic resonator into the crystal oscillator mounting

sockets (for the main clock and sub clock) on the MCU board. The MCU board has

one crystal oscillator mounting socket for the main clock (SC1-SC3) and another for

the sub clock (SC4-SC6). To distinguish them from each other, the board has the

"MAIN CLOCK" and "SUB CLOCK" labels printed near the main-clock socket and

sub clock socket, respectively. Mount the crystal oscillator along with two capacitors

on the MCU board. By use of a ceramic resonator these capacitors are nit required.
