A Power-on Reset (POR) pulse is generated by an On-chip detection circuit. The detection level is defined in Table 23. The POR is activated whenever VCC is below the detection level. The POR circuit can be used to trigger the start-up Reset, as well as to detect a failure in supply voltage. A Power-on Reset (POR) circuit ensures that the device is reset from Power-on. Reaching the Power-on Reset threshold voltage invokes the delay counter, which determines how long the device is kept in RESET after VCC rise if clone ic at87F52 firmware.

The RESET signal is activated again, without any delay, when VCC decreases below the detection level. An External Reset is generated by a low level on the RESET pin. Reset pulses longer than the minimum pulse width (see Table 23) will generate a reset, even if the clock is not running.

Shorter pulses are not guaranteed to generate a reset. When the applied signal reaches the Reset Threshold Voltage – VRST – on its positive edge, the delay counter starts the MCU after the Time-out period – tTOUT – has expired after unlock chip at87f55wd .

PIC16F54C has an On-chip Brown-out Detection (BOD) circuit for monitoring the VCC level during operation by comparing it to a fixed trigger level. The trigger level for the BOD can be selected by the BODLEVEL Fuses.

The trigger level has a hysteresis to ensure spike free Brown-out Detection. The hysteresis on the detection level should be interpreted as VBOT+ = VBOT + VHYST/2 and VBOT- = VBOT – VHYST/2. When the BOD is enabled, and VCC decreases to a value below the trigger level (VBOT-in Figure 29), the Brown-out Reset is immediately activated. When VCC increases above the trigger level (VBOT+ in Figure 29), the delay counter starts the MCU after the Time-out period tTOUT has expired before clone ic attiny11 software.

The BOD circuit will only detect a drop in VCC if the voltage stays below the trigger level for longer than tBOD.
