CONT: Continuous Conversion

Bit 15 0: When all bits 14 to 11 are '0', the temp sensor core goes immediately to shutdown mode. When all bits 14 to 11

are not '0', the temp sensor core stops when all enabled conversions are done. When this bit is '0', a one-shot

command can be triggered by writing a "1" to bit 14 of Configuration Register 1.

1: Continuous temperature conversion mode.

REN3: Remote Channel 3 Enable (TMP513 only)

Bit 14 0: Remote channel 3 disabled.

1: Remote channel 3 enabled.

REN2: Remote Channel 2 Enable

Bit 13 0: Remote channel 2 disabled.

1: Remote channel 2 enabled.

REN1: Remote Channel 1 Enable

Bit 12 0: Remote channel 1 disabled.

1: Remote channel 1 enabled.

LEN: Local Temperature Enable

Bit 11 0: Local temperature disabled.

1: Local temperature enabled.

RC: Resistance Correction

Bit 10 0: Resistance correction disabled.

1: Resistance correction enabled.

R2, R1, R0: Conversion Rate

Bits 9-7 These bits set the conversion rate as shown in Table 7.

(1) Shaded values are default.

(2) Conversion rate shown is for only one or two enabled measurement channels. When three channels

are enabled, the conversion rate is 2 and 2/3 conversions per second. When four channels are

enabled, the conversion rate is 2 per second.

(3) Conversion rate shown is for only one enabled measurement channel. When two channels are

enabled, the conversion rate is 4 conversions per second. When three channels are enabled, the

conversion rate is 2 and 2/3 conversions per second.
