10. TERMINAL FUNCTION
1. SCL
SCL terminal is a serial lock input terminal and used for TX/RX
control between master and slave.
2. SDA
SDA terminal is an input/output terminal and transfers the
address sent from the master device to slave and mutual data.
SDA output circuit employs the open drain, therefore the pull-up
resistor is requ Terminal ired.
3. A0, A1, A2
The terminals of A0, A1 and A2 are not used.
4. WP
The WP terminal controls writing operation. Reading only is
allowed when WP is high, and both reading and writing are
allowed when WP is low.
