POWER-ON RESET
An automatic reset can be obtained when V
DD
is turned on
by connecting the RESET pin to V
DDP
through a
10
μ
F capacitor, providing the V
DD
rise time does not
exceed 1 ms, and the oscillator start-up time does not
exceed 10 ms.
To ensure correct initialisation, the RESET pin must be
held high long enough for the oscillator to settle following
power-up, usually a few ms. Once the oscillator is stable,
a further 24 clocks are required to generate the reset (two
machine cycles of the microcontroller). Once the above
reset condition has been detected an internal reset signal
is triggered which remains active for 2048 clock cycles.
