Output of 32 kHz oscillator amplifier circuit
Input: Hardware Standby mode entry input active
low.
Caution: External pull-up to V
normal mode.
Output: Standby mode active low output following
Software Standby mode entry.
Note: In Standby mode all pins are in high
impedance except those marked Active in Stdby.
Stabilization for low power voltage regulator.
Requires external capacitors of at least 1µF
between V
Note: If the low power voltage regulator is
bypassed, this pin can be connected to an external
1.8V supply.
Stabilization for main voltage regulator. Requires
external capacitors of at least 10µF + 33nF
between V
