Abstract:
1. A method comprising: in response to receiving first mode control input to operate a digital controller integrated circuit in a first mode, configuring multiple pins of the digital controller integrated circuit as inputs to write data to memory in the digital controller integrated circuit, the digital controller integrated circuit being mounted on a circuit substrate; in response to receiving second mode control input to operate the digital controller integrated circuit in a second mode, configuring the multiple pins of the digital controller integrated circuit as outputs to control power supply circuitry residing on the circuit substrate; receiving first control input from an in-circuit programmer, the in-circuit programmer removably connected to communicate with the digital controller integrated circuit on the circuit substrate, the first control input received on a pin of the digital controller integrated circuit that is configured as an input pin in the first mode, the pin configured as an output pin in the second mode; and utilizing the first control input to at least partially derive the first mode control input indicating to operate the digital controller integrated circuit in the first mode.
