Access TH [A1h]
If R/
W
is "0", this command writes to the TH register. After issuing this command, the next two bytes
written to the DS1629, in the format described for thermostat set-points, will set the high temperature
threshold for operation of the ALRM output and TAF/TAL flags. If R/
W
is "1", the value stored in this
register is read back.
Access TL [A2h]
If R/
W
is "0", this command writes to the TL register. After issuing this command, the next two bytes
written to the DS1629, in the format described for thermostat set-points, will set the high temperature
threshold for operation of the ALRM output and TAF flag. If R/
W
is "1", the value stored in this register
is read back.
Access Memory [17h]
This command instructs the DS1629 to access the user-SRAM array, starting with the specified byte
address. Read/write depends upon the state of the R/
W
in the 2-wire control byte. The user can read/write
all 32 bytes in succession within one command sequence, with the pointer automatically wrapping from
1Fh to 00h; if the master attempts to read/write more than 32 bytes, the address pointer will wrap to the
1
st
byte after the 32
nd
is read/written and ACK’d by the master/slave. Refer to Figure 6 for command
protocol.
