3.5 OSCILLATION CIRCUIT
A clock oscillator, being installed, generates a system clock and an internal clock. Two clock supplying
methods are available including one to connect a ceramic oscillator and the other to input an external clock.
When using a ceramic oscillator, you are recommended to use CSTCS16.00MX0C3 (with a condenser)
manufactured by Murata Mfg. Co.. For input of an external clock, two methods are available,
one of which is to open XTAL terminal and the other of which is to input an antiphase clock in
XTAL terminal.
