ENABLE Allows a non zero voltage to be applied to the KOS VPP pin VPP 10V Controls the applied non zero voltage to be Vcc or 10 volts A P channel MOSFET Q2 switches VPP to 10 volts when VPP 10V is high For example if Q2 is not in the circuit a pair of emitter followers Q4 and Q7 can be connected so that the emitter of Q7 nearly equals the output voltage from the USD NAND gate If the NAND output is VCC the emitter of Q4 is a diode drop above VCC and the emitter of Q7 a diode drop below its base voltage or at VCC The same applies when the NAND output is low the emitter of Q7 is zero pulled to ground by R26 The NAND output is always equal to control signal VPP ENABLE The two intervening inversions Q8 and the NAND only serve to provide drive for LED D10 Also when VPP ENABLE is 0 diode D6 asserts direct control over Q3 to turn off MOSFET Q2 regardless of the state of signal VPP 10V If VPP ENABLE is 1 then VPP 10V determines whether MOSFET Q2 is on or off If VPP 10V is 0 then VPP equals VCC If VPP 10V is 1 then Q2 is on pulling VPP to 10 volts and cutting off Q7 When VPP 10V switches from 1 to 0 resistor R26 pulls down VPP until Q7 asserts control MUB KO KOS LCD Multi Use Board User s Manual 3 5 Hardware 3 6 NEC MUB KO KOS LCD Multi Use Board User s Manual NEC 4 1 Loopback Test 4 2 Resistors 4 8 A D Converter Power Special Features d The board has two jumper plugs JW3 and JW4 The dig
