Notes

95:88

SOT

0HEX

nd Order Term. This term is a 7-bit magnitude with sign.

SOT[7] = 1  negative

SOT[7] = 0  positive

SOT[6:0] = magnitude [0-127]

This term can apply to a 2

nd order Tcg, Tco or bridge correction.

(See Tc_cfg above.)

99:96

{SOT_cfg,

Pamp_Gain}

5HEX

Bits [99:98] = SOT_cfg

00 = SOT applies to Bridge

01 = SOT applies to Tcg

10 = SOT applies to Tco

11 = Prohibited

Bits [97:96] = Pre-Amp Gain

00 => 6

01 => 24 (default setting)

10 => 48

11 => 96

102:100

Diag_cfg

7HEX

This 3-bit term applies to diagnostic features

Diag_cfg[2]  enable output short circuit protection.

Diag _cfg[1]  enable sensor short checking.

Diag_cfg[0]  enables sensor connection checking.

105:103

Lock_ExtTemp

0HEX

EEPROM lock

011 or 110 => locked

All other

=> unlocked

When EEPROM is locked, the internal charge pump is disabled

and the EEPROM can never be programmed again.

Bit 105 (the MSB of this field) is also used for selecting external

temperature measurement.

000,001,010,011=>Internal PTAT used for temp

100,101,110,111=>External diode used for temp

112:106

Up_Clip_Lim

7FHEX

7-bit value used to select an upper clipping limit for the output. It

affects both analog and digital output. The 14-bit upper clipping

limit value is comprised of {11,Up_Clip_Lim[6:0],11111}. 127

different clipping levels are selectable between 75.19% and

100% of VDD.

119:113

Low_Clip_Lim

0HEX

7-bit value used to select a lower clipping limit for the output. It

affects both analog and digital output. The 14-bit lower clipping

limit value is comprised of {00,Low_Clip_Lim[6:0],00000}. 127

different clipping levels are selectable between 0% and 24.8%

of VDD.
