Registers

The ATS75 contains the following five registers:

Command Register

The Command Register is a one-byte (8-bit) write-only

indicates which of the other four registers (Temperature,

Configuration, T_HYST, or T_OS) 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.

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 anytime (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.

The Command Register is illustrated in Figure 3. The P1

and P0 bits of the Command Register determine which

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.
