3. Quick check of the operation of the equipment which uses AN6783S

1) Input to pin 5 a higher frequency than the fre-

quency with C and R, and the timer's time becomes

short. Since a capacitor of big capacitance is at-

tached at pin 5 at this moment, use a power am-

plifier which has an output of a totem pole type. (If

the output of a pulse generator is large enough, it

is not necessary.) But be careful to keep an input

waveform of 1.8 V or less.

2) Place RTEST in parallel with Rt only at the test to

lower the resistance, and an oscillation frequency

may be high and a timer interval can be short-

ened.
