REGISTERS

The ADT75 contains six registers: four are data registers, one is

the address pointer register, and the final register is the one-shot

is 8 bits wide while the rest are 16 bits wide. The temperature

value register is the only data register that is read only. Both a

read and write can be performed on the rest of the data registers

and on the one-shot register. On power-up, the address pointer

Address Pointer Register

This 8-bit write only register stores an address that points to one

of the four data registers and selects the one-shot mode. P0 and

P1 select the data register to which subsequent data bytes are

written to or read from. P0, P1, and P2 are used to select the

one-shot mode by writing 04h to this register. A zero should be

written to the rest of the bits.
