Data Sheet
Serial Read Operation
During a data read operation from the ADE7763, data is shifted
out at the DOUT logic output upon the rising edge of SCLK. As
is the case with the data write operation, a write to the commu-
nication register must precede a data read.
With the ADE7763 in communication mode (CS logic low),
first an 8-bit write to the communication register occurs. The
MSB of this byte transfer is a 0, indicating that the next data
transfer operation is a read. The LSBs of this byte contain the
address of the register that is to be read. The ADE7763 starts
shifting data out of the register upon the next rising edge of
SCLK—see Figure 85. At this point, the DOUT logic output
leaves its high impedance state and starts driving the data bus.
All remaining bits of register data are shifted out upon subsequent
SCLK rising edges. The serial interface also enters communica-
tion mode as soon as the read is complete. Then, the DOUT

logic output enters a high impedance state upon the falling edge
of the last SCLK pulse. The read operation can be aborted by
bringing the CS logic input high before the data transfer is
complete. The DOUT output enters a high impedance state
upon the rising edge of CS.
When an ADE7763 register is addressed for a read operation,
the entire contents of that register are transferred to the serial
port. This allows the ADE7763 to modify its on-chip registers
without the risk of corrupting data during a multibyte transfer.
Note that when a read operation follows a write operation, the
read command (i.e., write to communication register) should
not happen for at least 4 μs after the end of the write operation.
If the read command is sent within 4 μs of the write operation,
the last byte of the write operation could be lost. This timing
constraint is given as timing specification t 9 .
