This demo is based on the GD32307C-EVAL-V1.1 board, it shows the I2C programming
mode in slave receiving mode. In this demo, I2C0 is operated as slave receiver,
and the SCL line and SDA line of I2C0 interface are controled by the I/O pin
PB6 and PB7 respectively.

This demo shows the receving process of the slave. And it will store the
received data in the i2c_receiver array.

The demo doesn't perform the data transfer actually, which is due to no specific
master.In the specific application, we need config the master to start a data
transmission.In addition,the master and the slave may need to be connected by
the jumper if necessary.
