Registers
The FM75 contains the following five registers:
1.
Command Register
2.
Temperature Register
3.
Configuration Register
4.
Over-Limit-Signal Temperature Register (T
OS
)
5.
Hysteresis Temperature Register (T
HYST
)
All of these registers can be accessed by the user via the
digital serial interface at any time (see Serial Interface
Operation for instructions). A detailed description of these
registers and their functions is provided in the following
paragraphs. A diagram of the register hierarchy is shown in
Figure 2.
Command Register
The Command Register is a one-byte (8-bit) write-only
register. The data stored in the Command Register indicates
which of the other four registers (Temperature, Configura-
tion, T
OS
, or T
HYST
) the user intends to read from or
write to during an upcoming operation. In other words the
Command Register “points” to the selected register as shown
in Figure 2.
The Command Register is illustrated in Figure 3. The P1 and
P0 bits of the Command Register determine which register is
to be accessed as shown in Table 2. The six MSBs of the
Command Register must always be zero. Writing a 1 into
any of these bits will cause the current operation to be
terminated.
The Command Register retains pointer information between
operations. Therefore, this register only needs to be updated
once for consecutive read operations from the same register.
All bits in the Command Register default to zero at
power-up.
