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