Write Operation

Read Operation

Figure 59 shows the timing diagram for a write operation to the

ADT7518. Data is clocked into the registers on the rising edge

Figure 60 to Figure 62 show the timing diagrams necessary to

accomplish correct read operations. To read back from a reg-

ister, first write to the address pointer register with the address

of the register to be read from. This operation is shown in

Figure 60. Figure 61 shows the procedure for reading back a

single byte of data. The read command is first sent to the part

during the first eight clock cycles. During the following eight

clock cycles, the data contained in the register selected by the

address pointer register is output onto the D_OUTline. Data is

output onto the D_OUTline on the falling edge of SCLK. Figure 62

shows the procedure when reading data from two sequential

registers. Multiple data reads are possible in the SPI interface

mode as the address pointer register is autoincremental. The

address pointer register will autoincrement from 00h to 3Fh and

will loop back to start again at 00h when it reaches 3Fh.

of SCLK. When the

line is high, the DIN and DOUT lines

are in three-state mode. Only when the

goes from a high to a

low does the part accept any data on the DIN line. In SPI mode,

the address pointer register is capable of autoincrementing to

the next register in the register map without having to load the

address pointer register each time. In Figure 59, the register

address portion gives the first register that will be written to.

Subsequent data bytes will be written into sequential writable

registers. Thus, after each data byte has been written into a

the next available register. The address pointer register will

autoincrement from 00h to 3Fh and will loop back to start again

at 00h when it reaches 3Fh.
