The Configuration register is 8 bits, read/write, and
contains the SMBus timeout disable bit, fault queue
enable bit, the temperature alarm output polarity select
bits, the interrupt mode select bit, and the shutdown
bit. Registers T
HIGH
and T
LOW
are 16 bits, read/write,
and contain the values that trigger
ALERT
. Register
T
HYST
is 16 bits, read/write, and contains the values by
which the temperature must rise or fall beyond T
HIGH
or
T
LOW
, before
ALERT
deasserts.
Control Registers (MAX6635)
Seven registers control the operation of the MAX6635
(Figure 7 and Tables 2 through 7). The Pointer register
is the first addressed and determines which of the other
six registers is acted upon. The other six are the
Temperature, Configuration, High-Temperature
(T
HIGH
), Low-Temperature (T
LOW
), Maximum
Temperature (T
MAX
), and Hysteresis (T
HYST
) registers.
The temperature value is stored as 12 bits plus a sign
bit, read only, and contains the latest temperature data.
The true register length is 16 bits, with the lower three
used as status bits. The digital temperature data con-
tained in the temperature register is in
°
C, using a
two
’
s-complement format with 1LSB corresponding to
0.0625
°
C.
The Configuration register is 8 bits, read/write, and
contains the SMBus timeout disable bit, fault queue
enable bit, the temperature alarm output polarity select
bits, the interrupt mode select bit, and the shutdown
