beyond storing the register address
bytes received after the register address are data bytes.
The first data byte goes into the register selected by the
register address, and subsequent data bytes go into
subsequent registers
are transmitted before a STOP condition, these bytes
are stored in subsequent registers because the register
addresses autoincrement.
The serializer/deserializer are read using the internally
stored register address as an address pointer, the same
way the stored register address is used as an address
pointer for a write. The pointer autoincrements after each
data byte is read using the same rules as for a write. Thus,
a read is initiated by first configuring the register address
by performing a write
read consecutive bytes from the device, with the first data
byte being read from the register address pointed by
the previously written register address. Once the master
sends a NACK, the device stops sending valid data.

SCL clock stretching. While multiple masters can reside
on either side of the communication link, arbitration is not
provided. The connected masters need to support SCL
