condition
• Start condition
With SCL at High, SDA line goes from High to Low
• Stop condition
With SCL at High, SDA line goes from Low to High
(Under normal circumstances, SDA is changed when SCL is Low)
• Acknowledge bit The receiving IC has to pull down SDA line whenever receive slave data.
(The transmitting IC releases the SDA line just then transmit 8-bit data.)
