Output frequency preset by CTL1 to 6. (refer to the procedure for setting output frequency.) Constantly outputs the oscillation source frequency of builtin (c) FOUT : crystal unit. Stops output at RESET= “L”. (d) RESET : (pull-up resistor incorporated.) Used for the input terminal for testing. When CTL4 is H, (e) TEST : output will be 1000 times larger than the preset value at TEST= “H”. (pull-down resistor incorporated.) Serves as input terminal when using an external clock by (f) EXC (8640N only) : 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.) (a) CTL 1 to 6 : (b) OUT : (Note) Treatment of empty terminals. When RESET terminal is not used, this should be connected to VDD, and when TEST terminal, CSEL terminal, and CTL 1 to 6 terminals are not used, to GND.
