Crystal oscillators
The recommended crystal oscillator configuration is shown in Fig.6. The specified component values only apply to
crystals with a low equivalent series resistance of <40
.
System reset
Reset must be active from system power-up for >1 ms. Reset must also be active for >1 ms after the falling edge of sleep
as shown in Fig.7.
