5) Notes for power supply
V
CC
rises through the low voltage region in which internal circuit of IC and the controller are unstable, so that device
may not work properly due to an incomplete reset of internal circuit.
To prevent this, the device has the feature of P.O.R. and LV
CC
.
In the case of power up, keep the following conditions to ensure functions of P.O.R and LV
CC
.
(1) It is necessary to be “SDA=H” and “SCL=’L’ or ‘H’ ”.
(2) Follow the recommended conditions of t

(3) Prevent SDA and SCL from being “Hi-Z”.
In case that condition 1. and / or 2. cannot be met, take following actions.
A) Unable to keep condition 1. (SDA is “LOW” during power up.)
→
Control SDA, SCL to be “HIGH” as figure below.

B) Unable to keep condition 2.
→
After power becomes stable, execute software reset. (See page14 )
C) Unable to keep condition 1 and 2.
→
Follow the instruction A first, then the instruction B.
