Function of Location
Writing to this byte determines which of the two
40x8 EEPROM look-up tables is selected for
reading or writing.
01h (Table 01h selected)
02h (Table 02h selected)
POL — Analog Updating
TAU — Temperature/Address Update
TEN — Temperature Update Enable
AEN — Address Update Enable
Default setting is 0Fh, TAU = 1, TEN = 1, and
AEN = 1.
POL = 1 until power is high enough to guarantee
outputs from the analog temperature converter.
Once POL = 0, automated updates will begin.
TAU becomes a 1 after a temperature and
address update has occurred as a result of a
temperature conversion. The user can write this
bit to 0 and check for a transition from 0 to 1 in
order to verify that a conversion has occurred.
If TEN = 0, the temperature conversion feature
is disabled. The user sets the DAC in manual
mode by writing to addresses 70h and
71h to control DAC-V and DAC-G, respectively.
With AEN = 0 the user can operate in a test
mode. Address updates made from the
temperature sensor will cease. The user can load
a memory location into 64h and verify that the
values in locations 70h and 71h are the expected
user-defined values.
This byte contains the MSB of the 12-bit 2’s
complement temperature output from the
temperature sensor.
