Sequential Read
and sends additional clock pulses so that the device continues to output the next byte in sequence. To terminate the stream of bytes, the bus master
must not acknowledge the last byte, and must generate a Stop condition (refer to the Read Mode Sequence figure). The output data comes from
consecutive addresses, with the internal address counter automatically incremented after each byte output. After the last memory address, the
address counter 'rolls-over', and the device continues to output data from memory address 0x00.
Acknowledge in Read Mode
not drive Serial Data (SDA) Low during this time, the device terminates the data transfer and returns to an idle state to await the next valid START
condition. This has no effect on the TS operational status.

SA1, and SA0. In the event SA0 is in the high voltage state, the device interprets the voltage as a logic '1' at the pin. The Temperature Register Set
stores the temperature data, limits, and configuration values. All registers in the address space from 0x00 through 0x08 are 16-bit registers accessed
through block read and write commands as detailed in the TS Write Operation section.

This operation can be used after a Current Address Read or a Random Address Read. The bus master does acknowledge the data byte output,
For all Read commands to the SPD, the device waits, after each byte read, for an acknowledgment during the 9th bit time. If the bus master does
