DATA BITS
BIT NAME
RESET STATE
FUNCTION
D15*
T1AVGCTL
0
Channel 1 averaging-equation bit. This bit controls the averaging equation
for channel 1 while the device is in tracking mode. See Table 11a.
D[14:12]*
T1LIMIT[2:0]
000
Channel 1 difference-limiter bits. Set T1LIMIT[2:0] to enable the difference
limiter for channel 1 temperature averaging. See Table 11b.
D11
FIFOSTAT
0
If the FIFOSTAT bit is set to 1, the ALARM output is used to monitor data
flow into/out of the FIFO and EEPROM while in the message and LUT
streaming modes.
D10
ADCMON
0
ADC monitor enable bit. If ADCMON is set to 1, the result from the ADC
conversion is copied into the FIFO, from where it can be read over the
serial interface. If ADCMON = 0, the result is not copied into the FIFO.
ADCMON and AVGMON cannot be active at the same time.
D[9:8]
PG2SET[1:0]
00
PGA2 gain-setting bits. See Table 11c.
D[7:6]
PG1SET[1:0]
00
PGA1 gain-setting bits. See Table 11c.
D[5:4]
CKSEL[1:0]
00
Clock mode and
CNVST bits. See Table 11d.
D[3:2]
ADCREF[1:0]
00
ADC reference select bits. See Table 11e.
D[1:0]
DACREF[1:0]
00
DAC reference select bits. See Table 11f.

CHANNEL 1 AVERAGING EQUATION
0
Average = average + 1/16 difference.
