When the Watchdog times out, it will generate a short reset pulse of one CK cycle duration. On the falling edge of this pulse, the delay timer starts counting the Time-out period tTOUT. See “Watchdog Timer” on page 56. for details on operation of the Watchdog Timer.

PIC12C508A features an internal bandgap reference. This reference is used for Brown-out Detection, and it can be used as an input to the Analog Comparator or the ADC if crack protected ic atmega88v code.

The voltage reference has a start-up time that may influence the way it should be used. The start-up time is given in Table 26. To save power, the reference is not always turned

  1. The reference is on during the following situations:
  2. When the BOD is enabled (by programming the BODLEVEL [2..0] Fuse).
  3. When the bandgap reference is connected to the Analog Comparator (by setting the ACBG bit in ACSR).
  1. When the ADC is enabled.

Thus, when the BOD is not enabled, after setting the ACBG bit or enabling the ADC, the user must always allow the reference to start up before the output from the Analog Comparator or ADC is used.

To reduce power consumption in Power-down mode, the user can avoid the three conditions above to ensure that the reference is turned off before entering Power-down mode.

PIC12C508A has an Enhanced Watchdog Timer (WDT). The main features are:

  • Clocked from separate On-chip Oscillator
  • 3 Operating modes

– Interrupt

– System Reset

– Interrupt and System Reset

  • Selectable Time-out period from 16ms to 8s

· Possible Hardware fuse Watchdog always on (WDTON) for fail-safe mode.

The Watchdog Timer (WDT) is a timer counting cycles of a separate on-chip 128 kHz oscillator. The WDT gives an interrupt or a system reset when the counter reaches a given time-out value. In normal operation mode, it is required that the system uses the WDR – Watchdog Timer Reset – instruction to restart the counter before the time-out value is reached when crack protected ic atmega168 code.

If the system doesn’t restart the counter, an interrupt or system reset will be issued. In Interrupt mode, the WDT gives an interrupt when the timer expires. This interrupt can be used to wake the device from sleep-modes, and also as a general system timer.

One example is to limit the maximum time allowed for certain operations, giving an interrupt when the operation has run longer than expected. In System Reset mode, the WDT gives a reset when the timer expires. This is typically used to prevent system hang-up in case of runaway code before crack unlock microcontroller atmega168a eeprom.

The third mode, Interrupt and System Reset mode, combines the other two modes by first giving an interrupt and then switch to System Reset mode. This mode will for instance allow a safe shutdown by saving critical parameters before a system reset.
