POWER-ON RESET
Two reset inputs are present on the device, the RESET pin
being active HIGH and RESET pin being active LOW. Only
one of these inputs need be connected in the system as
they are ORed internally to the device and each pin has
the necessary pull-down (for RESET) and pull-up (for
RESET) resistors at the pad.
An automatic reset can be obtained when VDD is switched
on by connecting the RESET pin to VDDP through a 10 F
capacitor, providing the VDD rise time does not exceed
1 ms, and the oscillator start-up time does not exceed
10 ms.
Alternatively, a capacitor connected to VSSP with a suitable
pull-up to VDDP, (e.g. 10 F capacitor; 16 k resistor) can
be connected to the RESET pin.
To ensure correct initialisation, the RESET/RESET pin
must be held HIGH/LOW long enough for the oscillator to
settle following power-up, usually a few milliseconds
(application specific, typically 10 ms). Once the oscillator
is stable, a further 24 crystal clocks are required to
generate the reset. Once the above reset condition has
been detected, an internal reset signal is triggered (which
remains active for 2048 clock cycles).
