Serial Addressing
Each transmission consists of a START condition (Figure
6) sent by a master, followed by the MAX5952 7-bit
slave address plus R/W bit, a register address byte, one
or more data bytes, and finally a STOP condition.
START and STOP Conditions
Both SCL and SDA remain high when the interface is
not busy. A master signals the beginning of a transmis-
sion with a START (S) condition by transitioning SDA
from high to low while SCL is high. When the master fin-
ishes communicating with the slave, the master issues
a STOP (P) condition by transitioning SDA from low to
high while SCL is high. The STOP condition frees the
bus for another transmission.
Bit Transfer
Each clock pulse transfers one data bit (Figure 7). The
data on SDA must remain stable while SCL is high.
Acknowledge
The acknowledge bit is a clocked 9th bit (Figure 8) that
the recipient uses to handshake receipt of each byte of
data. Thus each byte effectively transferred requires 9
bits. The master generates the 9th clock pulse, and the
recipient pulls down SDA (or the SDAOUT in the 3-wire
interface) during the acknowledge clock pulse, so that
the SDA line is stable low during the high period of the
clock pulse. When the master transmits to the MAX5952,
the MAX5952 generates the acknowledge bit. When the
MAX5952 transmits to the master, the master generates
the acknowledge bit.
