In SX Microcontrollers, SX/B Compiler and SX-Key Tool, Zoot wrote:

You *have* to pull the oscillator/resonator when you want to debug. During debugging, it is required that the Key generates the clock signal *without* any other clock source in the circuit. Also try moving the programming header right next to the SX (just "north" of the chip so you have 4 open breadboard rows) and use very short wires between the prog. header and osc1/osc2 (and use the breadboard holes right next the pins -- breadboards are notorious for introducing stray capacitance into high frequency signal paths).
