Registers 0xC0 through 0xC2 are read only registers. 0xC0 has the chip and revid information

chipid (RO) – This ID 0x1 for all T06 parts.

revid (RO) – This ID 0x4 for revision B.

0xC1 and 0xC2 store the result of a temperature conversion.

Dspsigm – Bits [6:0] are the most significant byte of the last conversion result. The most significant bit is a

“fresh” bit, indicating the register has been updated since last read. Reading the Dspsigm register causes the

register Dspsigl to be loaded with the least significant byte of the last conversion result.

Dspsigl – The least significant byte of the last conversion result. Read Dspsigm first to align the bytes. The

complete 15b unsigned result is 256*Dspsigm[6:0]+Dspsigl[7:0].

A result of 16384 means the temperature is 55°C. More negative results mean lower temperature, and more

positive results mean higher temperature.

Temperature is calculated from the formula:

T (°C) = 55+ (256*Dspsigm[6:0]+Dspsigl[7:0] -16384)/160

This result can go from -47.4 to +157.39 °C. The recommended operating temperatures is -40°C to +125°C; so,

the result should never be out of range, but if operated beyond the ratings of the part, the result will clamp at

-47.4 to +157.39 °C (i.e., no underflow or over- flow).

Oneburst – Setting this bit initiates a single conversion. Set stop = 0 when setting oneburst = 1. The stop bit

will be set to 1 when the conversion completes.

Stop - Setting this bit causes the control state machine measurement loop to pause after the current

measurement burst completes. Once set, clearing this bit restarts the measurement loop.

Sleep - Setting this bit causes the part to enter sleep mode after the current measurement burst completes.

Once set, clearing this bit restarts the measurement loop.
