NOTES
1. MULTIPLE SEQUENTIAL REGISTERS CAN BE LOADED CONTINUOUSLY.
2. THE FIRST (LOWEST ADDRESS) REGISTER ADDRESS IS WRITTEN, FOLLOWED BY MULTIPLE 16-BIT DATA-WORDS.
3. THE ADDRESS AUTOMATICALLY INCREMENTS WITH EACH 16-BIT DATA-WORD (ALL 16 BITS MUST BE WRITTEN).
4. CS IS HELD LOW UNTIL THE LAST DESIRED REGISTER HAS BEEN LOADED.
5. 16-BIT COMMAND WORD SETTINGS FOR SEQUENTIAL WRITE OPERATION:
CW [15:11] = 11100 (ENABLE WORD)
CW [10] = 0 (R/W)
CW [9:0] = [AD9, AD8, AD7, AD6, AD5, AD4, AD3, AD2, AD1, AD0] (STARTING MSB-JUSTIFIED REGISTER ADDRESS)

NOTES
1. SDI BITS ARE LATCHED ON SCLK RISING EDGES. SCLK CAN IDLE HIGH OR LOW BETWEEN WRITE OPERATIONS.
2. THE 16-BIT CONTROL WORD MUST BE WRITTEN ON SDI: 5 BITS FOR ENABLE WORD, 1 BIT FOR R/W, AND 10 BITS FOR REGISTER ADDRESS.
3. THE REGISTER DATA IS READ BACK ON THE SDO PIN.
4. X DENOTES DON’T CARE.
5. XXX DENOTES HIGH IMPEDANCE THREE-STATE OUTPUT.
6. CS IS HELD LOW UNTIL ALL REGISTER BITS HAVE BEEN READ BACK.
7. 16-BIT COMMAND WORD SETTINGS FOR SINGLE READBACK OPERATION:
CW [15:11] = 11100 (ENABLE WORD)
CW [10] = 1 (R/W)
CW [9:0] = [AD9, AD8, AD7, AD6, AD5, AD4, AD3, AD2, AD1, AD0] (10-BIT MSB-JUSTIFIED REGISTER ADDRESS)

Reading Data
A read transaction begins when the master writes the command
word to the AD7147 with the read/write bit set to 1. The master
then supplies 16 clock pulses per data-word to be read, and the
AD7147 clocks out data from the addressed register on the SDO
line. The first data-word is clocked out on the first falling edge
of SCLK following the command word, as shown in Figure 51.
The AD7147 continues to clock out data on the SDO line if the
master continues to supply the clock signal on SCLK. The read
transaction finishes when the master takes CS high. If the AD7147
address pointer reaches its maximum value, the AD7147 repeatedly
clocks out data from the addressed register. The address pointer
does not wrap around.
