CONV<3:0>

bit 7

bit 0

Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as 0

-n = Value at POR

‘1’ = bit is set

‘0’ = Bit is cleared

x = Bit in unknown

SLEEP

= Active Mode or Standby mode, as controlled by R/S bit in Register 02h

= 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.
