The different kinds of resets all affect the internal registers of the microcontroller in different ways. To ensure reliable

continuation of normal program execution after a reset occurs, it is important to know what condition the microcontroller

is in after a particular reset occurs. The following table describes how each type of reset affects each of the

microcontroller internal registers.
