S = START Condition
P = STOP Condition
Sr = Repeated START Condition
D.C. = Don’t Care
ACK = Acknowledge, SDA pulled low during rising edge of SCL.
NACK = Not acknowledge, SDA left high during rising edge of SCL.
All data is clocked in/out of the device on rising edges of SCL.
= SDA transitions from high to low during period of SCL.
= SDA transitions from low to high during period of SCL.
