DESCRIPTION
This bit mirrors the state of the RST_OUT/OS pin when in OS mode.
'1' selects OS to be active-high '0' selects OS to be active-low.
'1' selects One-Time-Interrupt mode; '0' selects Comparator mode.
'1' selects 11-bit plus sign resolution temperature conversion; '0' selects the default 8-bit plus
sign resolution temperature conversion.
The lower four LSBs of the 11-bit plus sign temperature data. For 8-bit plus sign temperature
data, bit 7 is the LSB and bits 4 to 6 are undefined.

DESCRIPTION
Controls conversion rate:
'0' = Programmable conversion rate by the following formula:
Monitoring delay = (ms) = 1.42 × (8 × N + 6)
where N can be set by bits 7:0 in the Conversion Rate Count Register (address 0Bh).
'1' = Fixed monitoring delay of 728 ms.
