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
Not connected (not bonded)
Stabilisation for low power voltage regulator. Requires
external capacitors of at least 1µF between V
