Write Operation

Read Operation

Figure 63 shows the timing diagram for a write operation to the

ADT7516/ADT7517/ADT7519. Data is clocked into the reg-

Figure 64 to Figure 66 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 64. Figure 65 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 66

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 auto-incremental. The

address pointer register will auto-increment from 00h to 3Fh

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

isters on the rising edge 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 cap-

able of auto-incrementing to the next register in the register

map without having to load the address pointer register each

time. In Figure 63, the register address portion gives the first

written into sequential writable registers. Thus, after each data

byte has been written into a register, the address pointer register

auto-increments its value to the next available register. The

address pointer register will auto-increment from 00h to 3Fh

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