//
// FREE RUN, CLOCK IS TOGGLED AS CODE EXECUTES SEQUENTIALLY
// This version sets clock LOW then high again
// Then gets address via addr_high/addr_low tri-state buffers
// and reads data buffer. Then cycle repeats
// This fits better with the 65C02 timing diagram that shows
// address is stable on PHI2 rise, and data stable 25ns later
// Based on Pico_6502_v4_ehbasic.ino
//
// Pins are monitored in Wokwi Logic Analyzer and resulting VCD file viewed in PulseView (downsample factor = 50)
