Power-on reset
A power-on reset occurs when a positive transition is detected on VDD.
The power-on reset function is strictly for power turn-on conditions and
should not be used to detect drops in the power supply voltage. The
power-on circuitry provides a stabilisation delay (t
PORL
) from when the
oscillator becomes active. If the external RESET pin is low at the end of
this delay then the processor remains in the reset state until RESET
goes high. The user must ensure that the voltage on VDD has risen to a
point where the MCU can operate properly by the time t
PORL
has elapsed.
If there is doubt, the external RESET pin should remain low until the
voltage on VDD has reached the specified minimum operating voltage.
This may be accomplished by connecting an external RC-circuit to this
pin to generate a power-on reset (POR). In this case, the time constant
must be great enough (at least 100 ms) to allow the oscillator circuit to
stabilise.
