T
HYST
SETPOINT REGISTER
This 8-bit read/write register stores the temperature hysteresis
value for the T
HIGH
, T
LOW
, and T
CRIT
temperature limits. The
temperature hysteresis value is stored in straight binary format
using four LSBs. Increments are possible in steps of 1°C from
0°C to 15°C. The value in this register is subtracted from the
T
HIGH
and T
CRIT
values and added to the T
LOW
value to imple-
ment hysteresis.
ID REGISTER
This 8-bit read-only register stores the manufacturer ID in Bit 3
to Bit 7 and the silicon revision in Bit 0 to Bit 2.
