Explanation of terminal
(a) CTL 1 to 6 :
Programs dividing ratio. (pull-down resistor incorporated.)
(b) OUT :
Output frequency preset by CTL1 to 6.
(refer to the procedure for setting output frequency.)
(c) FOUT :
Constantly outputs the oscillation source frequency of builtin
crystal unit.
(d) RESET :
Stops output at RESET= “L”.
(pull-up resistor incorporated.)
(e) 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.)
(f) EXC (8640N only) : Serves as input terminal when using an external clock by
changing to the builtin oscillator.
Effective only when CSEL is H.
(g) CSEL (8640N only) : When this terminal is made H, the external clock is selected.
(pull-down resistor incorporated.)

and when TEST terminal, CSEL terminal, and CTL 1 to 6 terminals are not used, to GND.
