Revision1.1

8.5.56 Temperature Zone1 Gain and Offset Correction

Temperature gain and offset correction for Zone1 temperature monitoring.

Location: 7Dh

Type:

R/W (Becomes read-only when LOCK bit in the Configuration register is set.)

8.5.57 Temperature Zone2 Gain and Offset Correction

Temperature gain and offset correction for Zone2 temperature monitoring.

Location: 7Eh

Type:

R/W (Becomes read-only when LOCK bit in the Configuration register is set.)

Description

7-6

GAIN (Gain Correction). Controls the gain correction applied to Zone1 temperature data. The incoming

temperature data (after format modification, see Section 8.5.6 on page 157) is gain-corrected by multiplying by

the gain correction value.

Gain Correction Value

0 1:

1.0078125 dec. (1.0000001b)

0 0:

(no gain correction - default)

1 1:

0.9921875 dec. (0.1111111b)

1 0:

0.9843750 dec. (0.1111110b)

In case of a sensor connection error (for Remote Diode sensor only), the incoming temperature data is not correct-

ed according to GAIN field (the temperature data is set to 80h).

5-4

Reserved.

3-0

OFFSET (Offset Correction). Contains the offset correction value that is added (with sign) to the Zone1

temperature data. The incoming temperature data (after format modification, see Section 8.5.6 on page 157) is

offset-corrected.

The binary value of OFFSET field is interpreted as 4-bit, 2’s complement value, with a resolution of 1

°C/LSBit.

The incoming temperature data is not corrected according to OFFSET ﬁeld (i.e., the temperature data is set to 80h)

if a sensor connection error occurs (for Remote Diode sensor only).
