Communication starts with the master signaling the
beginning of a transmission with a START condition,
which is a high-to-low transition on SDA while SCL is
high. When the master has finished communicating with
the slave, the master issues a STOP condition, which is
a low-to-high transition on SDA while SCL is high. The
bus is then free for another transmission. Figures 7 and
8 show the timing diagrams for signals on the 2-wire
interface. The address byte, command byte, and data
byte are transmitted between the START and STOP con-
ditions. The SDA state is allowed to change only while
SCL is low, except for the START and STOP conditions.
Data is transmitted in 8-bit words and is sampled on the
rising edge of SCL. Nine clock cycles are required to
transfer each byte in or out of the MAX8709B since
either the master or the slave acknowledges the receipt
of the correct byte during the ninth clock. If the
MAX8709B receives the correct slave address followed
by R/ W = 0, it expects to receive 1 or 2 bytes of informa-
tion (depending on the protocol). If the device detects a
START or STOP condition prior to clocking in the bytes
of data, it considers this an error condition and disre-
gards all the data.
If the transmission is completed correctly, the registers
are updated immediately after a STOP (or RESTART)
condition. If the MAX8709B receives its correct slave
address followed by R/ W = 1, it expects to clock out the
register data selected by the previous command byte.
