VALUE REGISTERS
For data synchronization purposes, the MSB register should be read first if the user wants to read both MSB and
LSB registers. The LSB will be locked after the MSB is read. The LSB will be unlocked after being read. If the
user reads MSBs consecutively, each time the MSB is read, the LSB associated with that temperature will be
locked in and override the previous LSB value locked-in

7 SIGN RO Sign bit The Local temperature MSB value register
range is +127°C to 128°C. The value
6 64 RO bit weight 64°C
programmed in this register is used to
5 32 RO bit weight 32°C
determine a local temperature error event.
4 16 RO bit weight 16°C
3 8 RO bit weight 8°C
2 4 RO bit weight 4°C

7 1/2 RO bit weight 1/2°C (0.5°C) The Local Limit register range is 0°C to
127°C. The value programmed in this
6 1/4 RO bit weight 1/4°C (0.25°C)
register is used to determine a local
5 1/8 RO bit weight 1/8°C (0.125°C)
temperature error event.
4-0 0 RO Reserved – will report "0" when read.
