CONV<3:0>
bit 0
Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = bit is set
U = Unimplemented bit, read as 0
‘0’ = Bit is cleared
x = Bit in unknown
7
SLEEP
0 = Active Mode or Standby mode, as controlled by R/S bit in Register 02h
1 = SLEEP mode is enabled. This bit overrides R/S in Register 02h
6-4
Unimplemented: Read as ‘0’
3-0
CONV<3:0>: The Conversion Rate Register controls how often the temperature measurement
channels are updated and compared against the limits. This register is fully accessible at either
address (04H, 0AH). Determines the conversion rate as shown in Table 4-1.
