Read Data Format
Send the slave address with the R/W bit set to 1 to initi-
ate a read operation. The MAX11801/MAX11803
acknowledge receipt of its slave address by pulling
SDA low during the 9th SCL clock pulse. Transmitted
data is valid on the rising edge of SCL. A STOP condi-
tion can be issued after any number of read data bytes.
The address pointer should be preset to a specific reg-
ister before a read command is issued. The master pre-
sets the address pointer by first sending the
MAX11801/MAX11803’s slave address with the R/W bit
set to 0 followed by the selected register address. A
repeated START condition is then sent followed by the
slave address with the R/W bit set to 1. The MAX11801/
MAX11803 then transmit the contents of the selected
register. If the selected register supports autoincrement,
the register pointer automatically increments after trans-
mitting each data byte, making data in the next register
location available for access in the same transfer. Some
registers do not support autoincrement, usually
because they are at the end of a functional section or,
in the case of the FIFO, store multiple records.
The master acknowledges receipt of each data byte
received from the MAX11801/MAX11803 during the
“acknowledge clock period.” If the master requires
more data from the MAX11801/MAX11803, it brings the
acknowledge line low, indicating more data is expect-
ed. This sequence is repeated until the master termi-
nates with a not-acknowledge (~A) followed by a STOP
condition. Figure 27 illustrates the frame format for
