24.1.3 List of Pins
In order to stabilize V
DDL
, connect the V
DDL
pin to V
SS
via a capacitor (1
μF).

-
Positive power supply pin for the internal logic circuits
[Note]
Ÿ
In order to improve the noise resistance, place the inter-power supply bypass capacitor (C
V=
1 μF or
larger) and the the internal logic voltage (V
DDL
) capacitor (C
L
: 1 μF) in the vicinity of LSI on the user board
using the shortest possible wiring without passing through via holes.
Ÿ
The internal logic voltage (V
DDL
) is unavailable to use for an external device voltage.
24.2 Description of Operation
After power-on, V
DDL
becomes approximately 1.55 V.
In the STOP-D mode, V
DDL
is lowered to approximately 1.1 V to reduce the standby current. In the STOP-D mode, the
content of RAM and SFR is retained.
In the HALT, HALT-H, or STOP mode, V
DDL
is approximately 1.55 V.
Figure 24-3 shows the operation waveforms of the regulator.
See Chapter 4 "Power Management" and Chapter 6 "Clock Generation Circuit" for the STOP-D mode and stabilization
time.
