8.5.37 Temperature Low Limit Zone1

Temperature low limit for Zone1 temperature monitoring.

Location: 4Eh

Type:

R/W or RO (Becomes read-only when LOCK_LIM bit in the Monitoring Control register is set.)

8.5.38 Temperature High Limit Zone1

Temperature high limit for Zone1 temperature monitoring.

Location: 4Fh

Type:

R/W or RO (Becomes read-only when LOCK_LIM bit in the Monitoring Control register is set.)

8.5.39 Temperature Low Limit Zone2

Temperature low limit for Zone2 temperature monitoring.

Location: 50h

Type:

R/W or RO (Becomes read-only when LOCK_LIM bit in the Monitoring Control register is set.)

Description

7-0

LOW_LIMIT. The low limit value to which the associated temperature input data is compared. If the temperature

input data is lower than LOW_LIMIT, the corresponding bits in the HM Interrupt Status register, HM Sensor

Status Register and Status Register are updated/set (see Section 8.4.5 on page 144, Section 8.4.9 on page 148,

and Section 8.5.24 on page 165).

LOW_LIMIT format is the same as the format of the corresponding Temperature Reading Zone1 register (see

Section 37 on page 158). This format is dependent on the setting of the ZONE1_RANGE bit in the Monitor

Control Register (see Section 8.5.54 on page 176). The default value is 81h (-127

°C for 1°C resolution, -254°C

for 2

°C resolution).

Note: A value of 80h must not be used.

HIGH_LIMIT. The high limit value to which the associated temperature input data is compared. If the

temperature input data is higher than HIGH_LIMIT, the corresponding bits in the HM Interrupt Status register,

HM Sensor Status Register and Status Register are updated/set (see Section 8.4.5 on page 144, Section 8.4.9

on page 148, and Section 8.5.24 on page 165).

HIGH_LIMIT format is the same as the format of the corresponding Temperature Reading Zone1 register (see

Section 37 on page 158). This format is dependent on the setting of the ZONE1_RANGE bit in the Monitor

Control Register (see Section 8.5.54 on page 176). The default value is 7Fh (127

°C for 1°C resolution, 254°Cfor

°C resolution).

Note: A value of 80h must not be used.
