Enable NC: Do not connect to the external terminal. Explanation of Terminals Terminal Name Function CTL1 to 6 OUT Programs dividing ratio. (pull-down resistor incorporated) Output frequency preset by CTL1~6. (Refer to the setting procedure of output frequency) FOUT Constantly outputs the oscillation source frequency of built-in quartz crystal. RESET Stops output at RESET=“L”. (Pull up resistor incorporated) TEST Used for the input terminal for testing. When CTL4 is H, output will be 1000 times larger than the preset value at TEST-“H”. (Pull-down resistor incorporated) EXC Serves as input terminal when using an external clock by (8640N only) changing to the built-in oscillator. Effective only when CSEL is H. CSEL When this terminal is made H, the external clock is selected (8640N only) (Pull down resistor incorporated). Note: treatment of empty terminals. When RESET terminal is not used, this should be connected to VDD, when TEST terminal, CSEL terminal, and CTL1 to 6 terminals are not used, to GND.
