CHAPTER 2: POWER SUPPLY AND INITIAL RESET
Initial Reset
To initialize the S1C6S2N7 Series circuits, an initial reset
must be executed. There are three ways of doing this.
(1)Initial reset by the oscillation detection circuit
(2)External initial reset via the RESET pin
(3)External initial reset by simultaneous high input to pins
K00–K03 (depending on mask option)
Figure 2.2.1 shows the configuration of the initial reset
circuit.
