2) Set "A5
3) Set “00
4) Set “08
5) When a START condition is received, addresses are compared
6) •When the transmitted addresses are all "0" (general call), the ADR0 bit in the S10 register is set to "1"
7) Write dummy data to the S00 register.
8) After receiving 1-byte data, an ACK-CLK bit is automatically returned and an I
