• Manufacturer Part Number: HT83F10
• Description: Flash Type Voice 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. Note that where more than one package type exists the table will reflect the situation
for the larger package type.
