Bit Transfer
One data bit is transferred during each clock pulse.
The data on the SDA line must remain stable while SCL
is high ( Figure 4).
Acknowledge
The acknowledge bit is a clocked 9th bit that the recipi-
ent uses to handshake receipt each byte of data
( Figure 5). Therefore, each byte effectively transferred
clock pulse, and the recipient pulls down SDA during
the acknowledge clock pulse, so the SDA line remains
stable low during the high period of the clock pulse.
Slave Address
The MAX16805/MAX16806 have a 7-bit-long slave
address ( Figure 6, Table 1). The 8th bit following the 7-
bit slave address is the R/ W bit. Set the R/ W bit low for
a write command and high for a read command.
requires 9 bits. The master controller generates the 9th
