MEMORY
The DS2740 has memory space with registers for instrumentation, status, and control. When the MSB of
a two-byte register is read, both the MSB and LSB are latched and held for the duration of the Read Data
command to prevent updates during the read and ensure synchronization between the two register bytes.
For consistent results, always read the MSB and the LSB of a two-byte register during the same Read
Data command sequence.

SMODSLEEP Mode Enable. A value of 1 allows the DS2740 to enter Sleep mode when DQ is low for
2s. A value of 0 disables DQ related transitions to Sleep mode. The power-up default of SMOD = 0.
RNAOPRead Net Address Opcode. A value of 0 in this bit sets the opcode for the Read Net Address
command to 33h, while a 1 sets the opcode to 39h. The power-up default of RNAOP = 0.
XReserved bits.
