Setting of divider output
Baud rate generator
Setting of output frequency
(c) FOUT :
(d) RESET :
(e) TEST :
(f) EXC (8640N only) :
(g) CSEL (8640N only) :
Programs dividing ratio. (pull-down resistor incorporated.)
Output frequency preset by CTL1 to 6.
(refer to the procedure for setting output frequency.)
Constantly outputs the oscillation source frequency of builtin
crystal unit.
Stops output at RESET= “L”.
(pull-up resistor incorporated.)
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.)
Serves as input terminal when using an external clock by
changing to the builtin oscillator.
Effective only when CSEL is H.
When this terminal is made H, the external clock is selected.
(pull-down resistor incorporated.)
Treatment of empty terminals. When RESET terminal is not used, this should be connected to V
DD
,
and when TEST terminal, CSEL terminal, and CTL 1 to 6 terminals are not used, to GND.
