Control/Status Register (Continued)
Bit <5:4>: Temperature Resolution Bits. Selects one of four user-programmable temperature data resolutions as indicated in the
following table.
Bit <3>: Always write a zero to this Bit.
Bit <2:1>: Reserved Bits. Will return whatever was last written to them. Value is zero on power-up.
Bit <0>: Always write a zero to this Bit.
Reset State: 0000h
Reset Conditions: Upon Power-on Reset.
1.7.4 T
(Read/Write) Pointer Address: 82h (Read); 02h (Write)
Bit <15:5>: Upper-Limit Temperature byte. If the measured temperature, stored in the temperature register, exceeds this user-
programmable temperature limit, the OVERTEMP pin will assert and the T
Bit <4:0>: Reserved. Returns all zeroes when read.
Reset State: 4880h (+145°C)
Reset Conditions: Upon Power-on Reset.
1.7.5 T
(Read/Write) Pointer Address: 83h (Read); 03h (Write)
Bit <15:5>: Lower-Limit Temperature byte. If the measured temperature that is stored in the temperature register falls below this
user-programmable temperature limit, the OVERTEMP pin will not assert and the T
set to "1".
Bit <4:0>: Reserved. Returns all zeroes when read.
Reset State: 4600h (+140°C)
