[Note]
Ÿ
Use external pull-up resistors for SDA pin and SCL pin referring to the I
2
C bus specification. The internal
pull-up resistors unsatisfy the I
2
C bus specification. See the data sheet for each product for the value of
internal pull-up resistors.
Ÿ
Do not connect multiple master devices on the I
2
C bus.
