can be triggered by the watchdog or by external low level at RESET pin. If neither POR nor watchdog
reset are activated, an internal current source of typ. 30
μ
A is connectedto the RESET pin. An external
capacitor connectedbetween RESET and ground can extend the power on reset periodif required (see
Fig. 2).
When the regulatedpower supply voltage VCC becomes sufficient at power up, the main oscillator starts

to operate and generates the main clock signal MAINCLK. A counter provides a delay of 2048 clock cy-
cles between the detection of high level at RESET pin and the release of the reset for the CPU and the
peripheral logic modules. This is to allow the oscillator to be completely stabilized before the execution
of the firstinstruction as well as a safereset also for short pulses at RESETpin.
