Input: Hardware Standby mode entry input active low.

Caution: External pull-up to V33 required to select nor-

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

X Reset input

VSSBKP

X Stabilisation for low power voltage regulator.

V18BKP

Stabilisation for low power voltage regulator. Requires

external capacitors of at least 1µF between V18BKP and

VSS18BKP. See Figure 5.

Note: If the low power voltage regulator is bypassed,

this pin can be connected to an external 1.8V supply.

G5 V18

Stabilisation for main voltage regulator. Requires exter-

nal capacitors of at least 10µF + 33nF between V18 and

VSS18. See Figure 5.

VSS18

Stabilisation for main voltage regulator.
