Initialization Setting
The device initialization is started by setting the reset pin (XRS) to low level. The timing should satisfy the
conditions noted below.
(1) During power-on (VDD = 3.0 to 3.6V, Topr = –40 to +85°C)
XPWRS should rise simultaneously with the power supply. XRS should rise 100ms or more after the power
supply and XPWRS have risen.

(2) Initialization during operation (VDD = 3.0 to 3.6V, Topr = –40 to +85°C)
The internal registers can be initialized during operation by setting the XRS signal to low level for 100µs or
more. Keep the XPWRS signal at high level at this time. (The internal memory value is held.)
