Reset
17.1 Theory of Operation
The LZ87010 has an active-HIGH RESET signal with an internal pull-down resistor (with
a nominal value of 90 kΩ).
The recommended RESET pulse width is 38 HFCLK cycles, starting after VDD and the
system oscillators are stable.
For debugging, a simple push-button switch between RESET and VDD gives good results
without additional circuitry.
