Write Operation
Figure 63 shows the timing diagram for a write operation to the
ADT7516/ADT7517/ADT7519. Data is clocked into the reg-
isters on the rising edge of SCLK. When the CS line is high, the
DIN and DOUT lines are in three-state mode. Only when the
CS 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
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 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.
Read Operation
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
OUT
line. Data is
output onto the D
OUT
line 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
