4.4. Power supply monitoring

There is an Analog to Digital Converter (ADC) and eight CT_R4F_ADC registers in the CT-R4F PLD that enable specific ARM Cortex-R4F test chip currents and voltages to be monitored. Each channel of the ADC is allocated a register to provides a digital value proportional to the current or the voltage supplied. The contents of these registers is transferred continually to the baseboard using the 4-wire serial interface.
