DS1856
A2D Value1
Mon3 Meas................ <R-all><W-NA><0000h> Unsigned voltage measurement.
Reserved .................... <R-all><W-NA><0000h>
Status ......................... <R-all><W-see bits><conditional>
a)
Rhiz.................... <R-all><W-NA><1b> High when resistor outputs are high impedance.
b)
Soft Hiz.............. <R-all><W-all><0b> Setting this bit will make resistor outputs high
impedance.
c)
Reserved ............ <R-all><W-NA><0b>
d)
TxF ................... <R-all><W-NA><conditional> Reflects the logic level to be output on pin Out1.
e)
RxL ................... <R-all><W-NA><conditional> Reflects the logic level to be output on pin Out2.
f)
Rdyb................... <R-all><W-NA>< VCC dependant > Ready Bar. When the supply is
above the Power-On-Analog (POA) trip point, this bit is active LOW.
Thus, this bit reads a logic One if the supply is below POA or too low
to communicate over the 2-wire bus.
Update ....................... <R-all/W-all><00h> Status of completed conversions. At Power-On,
these bits are cleared and will be set as each conversion is completed.
These bits can be cleared so that a completion of a new conversion
may be verified.
a)
Temp Rdy .......... Temperature conversion is ready.
b)
VCC Rdy............. VCC conversion is ready.
c)
Mon1 Rdy.......... Mon1 conversion is ready.
d)
Mon2 Rdy.......... Mon2 conversion is ready.
e) Mon3 Rdy.......... Mon3 conversion is ready.
Status
Alarm0 ....................... <R-all><W-NA><10h> High Alarm Status bits.
a)
Temp Hi............. High Alarm Status for Temperature measurement.
b)
Temp Lo ............ Low Alarm Status for Temperature measurement.
c)
VCC Hi .............. High Alarm Status for VCC measurement.
d)
VCC Lo .............. Low Alarm Status for VCC measurement. This bit is set when theVCC
supply is below the POA trip point value. It clears itself when a VCC
measurement is completed and the value is above the low threshold.
e)
MON1 Hi........... High Alarm Status for MON1 measurement.
f)
MON1 Lo .......... Low Alarm Status for MON1 measurement.
g)
MON2 Hi........... High Alarm Status for MON2 measurement.
h)
MON2 Lo .......... Low Alarm Status for MON2 measurement.
Alarm1 ....................... <R-all><W-NA><00h> Low Alarm Status bits.
a)
MON3 HI........... High Alarm Status for MON3 measurement.
b)
MON3 Lo .......... Low Alarm Status for MON3 measurement.
c)
Mint ................... Maskable Interrupt. If an alarm is present and the alarm is enabled then
this bit is high. Otherwise this bit is a zero.
Reserved .................... <R-all><W-NA><00h>.
Warning0 ................... <R-all><W-NA><00h> High Warning Status bits.
a)
Temp Hi............. High Warning Status for Temperature measurement.
b)
Temp Lo ............ Low Warning Status for Temperature measurement.
c)
VCC Hi ............. High Warning Status for VCC measurement.
