clock pulse
Notes 1. Use this in a voltage range of 4.5 V ≤ V
2. TI000/INTP0/P30:
TI000/ANI0/TOH1/P20: 78K0S/KY1+ and 78K0S/KU1+ microcontrollers
Cautions 1. Connect the AV
microcontrollers).
2. Connect the AV
3. Leave all unused pins open (unconnected), except for the pins shown in the circuit diagram
and the AV
