The data byte has the most significant bit first. At the end of a read, the LM89 can accept either acknowledge or
No Acknowledge from the Master (No Acknowledge is typically used as a signal for the slave that the Master has
read its last byte). It takes the LM89 31.25ms to measure the temperature of the remote diode and internal diode.
When retrieving all 10 bits from a previous remote diode temperature measurement, the master must insure that
all 10 bits are from the same temperature conversion. This may be achieved by using one-shot mode or by
setting the conversion rate and monitoring the busy bit such that no conversion occurs in between reading the
MSB and LSB of the last temperature conversion.
