HT46R064D/065D/066D
Enhanced A/D Type 8-Bit OTP MCU with LED Driver
The different kinds of resets all affect the internal registers of the microcontroller in different ways. To
ensure reliable continuation of normal program executio n 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.
