Table 13 shows the hexadecimal values (in sign-and-magnitude
format) that are downloaded to the AD7760 to realize this filter.
The table is also split into the bytes that are summed to produce
the checksum. The checksum generated from these coefficients
is 0x0E6B.

Checksum. Wait (0.5 × tICLK × number of unused
coefficients) for AD7760 to write 0s to the remaining
unused coefficients.
0x0001
Address of control register.
0x0879
Control register data. Set read status and maintain
filter length and decimation settings. Read contents
of status register. Check Bit 7 (DL_OK) to determine
if the filter was downloaded correctly.
