Note: Unless otherwise specified, the state of the registers is not defined when power is first applied.
Temperature Registers (11h–12h)
Temperature is represented as a 10-bit code with a res-
olution of +0.25°C and is accessible at location 11h
and 12h. The temperature is encoded in two’s comple-
ment format. The upper 8 bits are at location 11h, and
the lower 2 bits are in the upper nibble at location 12h.
Upon power reset, the registers are set to a default
temperature of 0°C and the controller starts a tempera-
ture conversion. New temperature readings are stored
in this register.
FRAM Address Map
During a multibyte access, the address pointer wraps
around to location 00h when it reaches the end of the
register space.
