1. POR = 0xFC, Lock = Y, SW Reset = Y.
2. +1.5V can be monitored on Pin 28 and 29 only when both are configured as +1.5V inputs. This means that +1.5V is measured on both pins

or on neither. +1.5V monitoring cannot be combined with another function on the other pin. For example, if Pin 29 is configured as +1.5V,
then THERM1 cannot be selected on Pin 28, because they share the same selection bits.
