DESCRIPTION
0A
R
0001 1110
(30癈)
Local temperature data:
This register contains the 8 MSBs of the local temperature measurement.
0B
R
0001 1110

Remote temperature data:
This register contains the 8 MSBs of the local temperature measurement.
0D
R/W

Local temperature offset:
Bit 7: Sign bit; when zero, the offset value in bits [3:0] is added to the measured local
  temperature reading. When this bit is 1, the offset value in bits [3:0] is subtracted
  from the local temperature reading.
Bits [6:4] Unused. This bits normally reads back zeros.
Bits [3:0] Offset value. This is added to or subtracted from the measured local
  temperature reading.
0E
R/W
0000 0000
Remote temperature offset:
Bit 7: Sign bit: When 0, the offset value in bits [3:0] is added to the measured remote
  temperature reading. When this bit is 1, the offset value in bits [3:0] is subtracted
  from the remote temperature reading.
Bits [6:4] Unused: These bits normally read back zeros.
Bits [3:0] Offset value: This is added to or subtracted from the measured remote
  temperature reading.

Fan tachometer high-limit register:
Contains the limit of the fan-speed measurement. It detects a stalled fan if the
measured fan-speed data (reg_08h; proportional to fan period) is larger than the limit.
14
R/W
0011 1100
(60癈)
Local temp high limit:
Contains the local high-temperature interrupt limit.
15
R/W
0000 0000
(0癈)
Local temp low limit:
Contains the local low-temperature interrupt limit.
16
R/W
0100 0110
(70癈)
Local temp THERM limit:
Contains the local high-temperature limit for the THERM output. Default is +70癈 for
the MAX6663/MAX6664; CRIT0 and CRIT1 determine the default value for the
MAX6653 (see Table 1).
18
R/W
0101 0000
(80癈)
Remote temp high limit:
Contains the remote high-temperature interrupt limit.
19
R/W
0000 0000
(0癈)
Remote temp low limit:
Contains the remote low-temperature interrupt limit.
1A
R/W
0110 0100
(100癈)
Remote temp THERM limit:
Contains the remote high-temperature limit for the THERM output. Default is +100癈
for the MAX6663/MAX6664; CRIT0 and CRIT1 determine the default value for the
MAX6653 (see Table 1).
1B
R/W
0101 1111
(95癈)
Local temp shutdown limit:
Contains the local high-temperature limit for the SDL output. CRIT0 and CRIT1
determine the default value for the MAX6653 (see Table 1).
1C
R/W
0111 1101
(125癈)
Remote temp shutdown limit:
Contains the remote high-temperature limit for the SDR output. CRIT0 and CRIT1
determine the default value for the MAX6653 (see Table 1).
