• Description: Enhanced I/O Type 8-Bit OTP MCU
• Manufacturer: HOLTEK [Holtek Semiconductor Inc]

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.
