DS1672
(R/ W ), which for a read is a 1. After receiving and decoding the address byte the DS1672 inputs an
Acknowledge on the SDA line. The DS1672 then begins to transmit data starting with the register
address pointed to by the register pointer. If the register pointer is not written to before the initiation
of a read mode the first address that is read is the last one stored in the register pointer. The DS1672
must receive a not acknowledge to end a read.
