register, at address 60h, provides 1/2°C resolution for temperatures between 0°C and 127 1/2°C,
formatted as follows:
64°C 32°C 16°C
8°C
4°C
2°C
1°C 1/2°C
The second register, at address 61h, provides 1°C resolution over the -40°C to +85°C range, formatted as
follows in the binary two’s complement coding.
7-BIT BINARY TEMP READING,

SIGN BIT -0 FOR POSITIVE,
1 FOR NEGATIVE
STATUS/CONTROL REGISTER (62h-63h)
The status register is a 2-byte register at addresses 62h and 63h (consisting of SRAM). Address 62h is the
least significant byte of the status register, and is currently the only address with defined status bits; the
other byte at address 63h is reserved for future use. The status register is formatted as follows:

Temperature Busy flag. 1 = temperature conversion in progress; 0 = temperature
conversion complete, valid data in temperature register.
NVB =
nonvolatile memory busy flag. 1 = Copy from scratchpad to NV RAM in progress,
0 = nonvolatile memory is not busy. A copy to NV RAM may take from 2 ms to 10 ms
(taking longer at lower supply voltages).
LOCK =
NV1 Locked flag. 1 indicates that NV1 is locked; 0 indicates that NV1 is unlocked.
