TABLE 5-3:
The binary value in this register represents ambient temperature following a conversion cycle.
TABLE 5-4:
TABLE 5-5:
In the TEMP, T
value represents one-half degree (Celsius). The value
is in 2’s – complement binary format such that a read-
ing of 000000000b corresponds to 0°C. Examples of
this temperature to binary value relationship are shown
in Table 5-6.
