REMOTE TEMPERATURE OFFSET REGISTERS (RTOHB and RTOLB)
Table 11. REMOTE TEMPERATURE OFFSET REGISTERS (RTOHB) (Read/Write Address 11h):
BIT D7 D6 D5 D4 D3 D2 D1 D0
Value SIGN 64 32 16 8 4 2 1
For RTOHB: Remote Temperature Offset High Byte. Power up default is LHIGH = RHIGH = 0°C. 1LSB = 1°C.
Two's complement format.
Table 12. REMOTE TEMPERATURE OFFSET REGISTERS (RTOLB) (Read/Write Address 12h):
BIT D7 D6 D5 D4 D3 D2 D1 D0
Value 0.5 0.25 0.125 0 0 0 0 0
For RTOLB: Remote Temperature Offset High Byte. Power up default is 0°C. 1LSB = 0.125°C. Two's
complement format.
The offset value written to these registers will automatically be added to or subtracted from the remote
temperature measurement that will be reported in the Remote Temperature registers.
LOCAL and REMOTE T_CRIT REGISTERS (RCS and LCS)
Table 13. LOCAL and REMOTE T_CRIT REGISTERS (RCS and LCS) (Read/Write Address 20h, 19h):
BIT D7 D6 D5 D4 D3 D2 D1 D0
Value SIGN 64 32 16 8 4 2 1
D7–D0: T_CRIT setpoint temperature data. Power up default is T_CRIT = 85°C. 1 LSB = 1°C, two's complement
format.
T_CRIT HYSTERESIS REGISTER (TH)
Table 14. T_CRIT HYSTERESIS REGISTER (TH) (Read and Write Address 21h):
BIT D7 D6 D5 D4 D3 D2 D1 D0
Value 16 8 4 2 1
D7–D0: T_CRIT Hysteresis temperature. Power up default is TH = 10°C. 1 LSB = 1°C, maximum value = 31.
