Error Monitor Threshold Setting
Threshold Voltage is proportional to AVDD voltage. This value is set in digital code.
The threshold voltage is a 12bit straight binary code which the full scale is AVDD/3 (11V@AVDD=3.3V). The
monitored voltage is multiplied by 0.3 by an external resistor and input to the voltage monitoring pin. Therefore, the
threshold voltage range is from +100mV/3(=+30mV) to +900mV/3(=+300mV) at the input pin.
