PACKET ERROR CHECKING
To verify that data has been received correctly in noisy environ-
ments, the AD5362/AD5363 offer the option of error checking
based on an 8-bit (CRC-8) cyclic redundancy check. The device
controlling the AD5362/AD5363 should generate an 8-bit
checksum using the polynomial C(x) = x8 + x2 + x1 + 1. This is
added to the end of the data-word, and 32 data bits are sent to
the AD5362/AD5363 before taking SYNC high. If the AD5362/
AD5363 see a 32-bit data frame, an error check is performed
when SYNC goes high. If the checksum is valid, the data is
written to the selected register. If the checksum is invalid, the
packet error check (PEC) output goes low and Bit 3 of the
control register is set. After reading the control register, Bit 3
is cleared automatically and PEC goes high again.

CHANNEL ADDRESSING AND SPECIAL MODES
If the mode bits are not 00, the data-word D15 to D0 (AD5362)
or D13 to D0 (AD5363) is written to the device. Address Bit A4
to Address Bit A0 determine which channels are written to, and
the mode bits determine to which register (X1A, X1B, C, or M)
be written to the X1A register when the A/B bit in the control
register is 0, or to the X1B register when the A/B bit is 1.
The AD5362/AD5363 have very flexible addressing that allows
the writing of data to a single channel, all channels in a group,
or all channels in the device.
Table 14 shows which groups and which channels are addressed
for every combination of Address Bit A4 to Address Bit A0.
