030598 12/27
I/O pin, the DS1820 waits 15–60
μ
s and then transmits
the presence pulse (a low signal for 60–240
μ
s).
MEMORY COMMAND FUNCTIONS
The following command protocols are summarized in
Table 2, and by the flowchart of Figure 10.
Write Scratchpad [4Eh]
This command writes to the scratchpad of the DS1820,
starting at address 2. The next two bytes written will be
saved in scratchpad memory, at address locations 2
and 3. Writing may be terminated at any point by issuing
a reset.
