restoring the CLKIN input and setting the ASUSPEND bit to

ensure that the data bits received in the last serial read operation
are not corrupted. The 6-bit checksum register is reset before
the first bit (MSB of the register to be read) is put on the DOUT
pin. During a serial read operation, when each data bit becomes
available upon the rising edge of SCLK, the bit is added to the
checksum register. At the end of the serial read operation, the
content of the checksum register is equal to the sum of all ones
previously read in the register. Using the checksum register, the
user can determine if an error has occurred during the last read
operation. Note that a read to the checksum register also
generates a checksum of the checksum register itself.
Figure 80. Addressing ADE7763 Registers via the Communication Register
The communication register is an 8-bit-wide register. The MSB
determines whether the next data transfer operation is a read or
a write. The 6 LSBs contain the address of the register to be
accessed—see the Communication Register section for a more
detailed description.
read and write operation, respectively. A data transfer is complete
when the LSB of the ADE7763 register being addressed (for a
write or a read) is transferred to or from the ADE7763. When
