is written into the slave's address pointer. Following an acknowledge by the slave, the master is allowed to write up to sixteen bytes of
data into the addressed register before the register address pointer overflows back to the beginning address. An acknowledge by the
device between each byte of data must occur before the next data byte is sent.
Registers are updated every time the device sends an acknowledge to the host. The register update does not wait for the STOP
condition to occur. Registers are therefore updated at different times during a sequential register write.
5.2.5. Sequential Register Read Procedure
Sequential read operations allow the master to read from each register in order. The register pointer is automatically incremented by
one after each read. This procedure is more efficient than the random register read if several registers must be read.
To perform a read procedure, the R/W bit that is transmitted after the seven-bit address is a logic-low, as in the register write procedure.
This indicates to the addressed slave device that a register address will follow after the slave device acknowledges its device address.
The register address is then written into the slave's address pointer.
Following an acknowledge by the slave, the master generates a repeated START condition. The repeated START terminates the write
procedure, but not until after the slave's address pointer is set. The slave address is then resent, with the R/W bit set this time to a
logic-high, indicating to the slave that data will be read. The slave will acknowledge the device address, and then transmits all 16 bytes
of data starting with the initial addressed register. The register address pointer will overflow if the initial register address is larger than
zero. After the last byte of data, the master does not acknowledge the transfer but does generate a STOP condition.
