WRITE OPERATIONS
For a write operation, the device requires a slave byte and
an address byte. The slave byte specifies the particular
device on the I
2
C bus that the master is writing to. The
address specifies one of the registers in that device. After
receipt of each byte, the device responds with an
acknowledge, and awaits the next eight bits from the master.
After the acknowledge, following the transfer of data, the
master terminates the transfer by generating a stop
condition. See Figure 12.
When receiving data from the master, the value in the data
byte is transferred into the register specified by the address
byte on the falling edge of the clock following the 8th data bit.
After receiving the acknowledge after the data byte, the
device automatically increments the address. So, before
sending the stop bit, the master may send additional data to
the device without re-sending the slave and address bytes.
After writing to address 0AH, the address “wraps around” to
address 0. Do not continue to write to addresses higher than
address 08H, since these addresses access registers that
are reserved. Writing to these locations can result in
unexpected device operation.
Read Operations
Read operations are initiated in the same manner as write
operations with the host sending the address where the read
is to start (but no data). Then, the host sends an ACK, a
repeated start, and the slave byte with the LSB=1. After the
device acknowledges the slave byte, the device sends out
one bit of data for each master clock. After the slave sends
eight bits to the master, the master sends a NACK (Not
acknowledge) to the device, to indicate the data transfer is
complete, then the master sends a stop bit. See Figure 13.
After sending the eighth data bit to the master, the device
automatically increments its internal address pointer. So the
master, instead of sending a NACK and the stop bit, can
send additional clocks to read the contents of the next
register - without sending another slave and address byte.
If the last address read or written is known, the master can
initiate a current address read. In this case, only the slave
byte is sent before data is returned. (See Figure 13.)
