Z8Plus OTP Microcontroller
CLOCK
The Z8Plus MCU derives its timing from on-board clock
circuitry connected to pins
circuitry consists of an oscillator, a glitch filter, and a di-
vide-by-two shaping circuit. Figure 12 illustrates the clock
circuitry. The oscillator’s input is

By selecting the
user interface (GUI), the circuit may instead be driven by
an external Resistor and Capacitor (
