78 / 108 page  HT56R62/HT56R65 HT56R642/HT56R644/HT56R654/HT56R656 Rev. 1.00 78 July 20, 2009 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. Note that where more than one package type exists the table will reflect the situation for the larger package type.
