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:

(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.
