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 Local Value Registers Register Name Command Read/ D7 D6 D5 D4 D3 D2 D1 D0 POR Byte Write Default (Hex) (Hex) Local Temp MSB 0x10 RO SIGN 64 32 16 8 4 2 1 – Local Temp LSB 0x20 RO 1/2 1/4 1/8 0 0 0 0 0 – Bit(s) Bit Name Read/ Description Write 7 SIGN RO Sign bit The Local temperature MSB value register range is +127°C to −128°C.
