[1] A = 100% serial test, B = Operating parameter, C = Only used for data characterization (cpk), D = Value guaranteed by design
[2] No active watchdog reset
[3] The nominal V_CC voltage is measured at V_SUP =12V. If the V_CC voltage is 100mV below its nominal value then the voltage drop is
V_D = V_SUP – V_CC.
