Functional Description
DONE
Read Only
At power-up, DONE = 1. (Unless AUTOC = 1)
DONE = 0Temperature conversion is in progress.
DONE = 1Temperature conversion is complete.
NVB
Read Only
At power-up, NVB = 0
NVB = 1Write to an E
2
memory cell is in progress
NVB = 0Nonvolatile memory is not busy.
THF
Read/Write
At power-up, THF = 0
THF = 1The measured temperature has reached or exceeded the value
stored in the T
H
register at anytime since power-up or since the bit was last
cleared. THF remains a 1 until the power is cycled or it is overwritten with a
0 by the user.
TLF
Read/Write
At power-up, TLF = 0
TLF = 1The measured temperature has met or fallen below the value
stored in the T
L
register at anytime since power-up or since the bit was last
cleared. TLF remains a 1 until the power is cycled or it is overwritten with a
0 by the user.
R1
*
Read/Write
Used to set conversion resolution (see Table 6).
Factory state = 1
R0
*
Read/Write
Used to set conversion resolution (see Table 6).
Factory state = 1
AUTOC
*
Read/Write
Determines whether the DS620 powers up idle or converting.
Factory state = 0
AUTOC = 1DS620 powers-up converting temperature.
AUTOC = 0DS620 powers-up idle.
1SHOT
*
Read/Write
Configures temperature conversion mode. Factory state = 0
1SHOT = 1: One-shot mode
For AUTOC = 0, the device powers up idle The Start Convert
command causes a single temperature conversion and then the
device returns to a low-power standby state.
If AUTOC = 1, the A1 pin is reconfigured as a conversion trigger for
standalone operation and the device powers up and performs 1
conversion. Single conversions can be initiated using the Start
Convert command or by toggling A1 high.
1SHOT = 0: Continuous conversion mode
For AUTOC = 0, the Start Convert command initiates continuous
conversions.
For AUTOC = 1, the device powers up performing continuous
conversions. Note: Changing the 1SHOT bit to 1 while continuous
conversions are in progress does not stop the conversions. A Stop
Convert command must first be issued after which one-shot
