AD7280A
CRC Calculation Example 3
This example shows the breakdown of a 32-bit register read
from the low byte of the control register of the master device,
that is, Device 0.
The CRC is computed in the AD7280A on Bits[D31:D10], that
is, the device address, the register address, the register data, two
reserved zero bits, and the write acknowledge bit. The
calculated CRC is sent along with Bits[D31:D10] and
Bits[D1:D0] to the DSP/microprocessor.
The data received from the AD7280A is as follows:
0000 0001 1100 0010 1000 0110 0110 1000 (0x01C28668).
? Device address: 00000 (0x00)
? Register address: 001110 (0x0E)
? Register data: 00010100 (0x14)
? Reserved 0s: 0 (0x0)
? Write acknowledge: 1 (0x1)
? CRC: 10011010 (0x9A)
? Reserved 0s: 0 (0x0)
The CRC bits are computed again in the DSP/microprocessor
on Bits[D31:D10] of the data that is read back from the AD7280A.
The data input to the CRC algorithm is, therefore,
0000000111000010100001 (0x0070A1).
Following the completion of the calculation, the value of
CRC Calculation Example 4
This example shows the breakdown of a 32-bit conversion result
read from the Cell Voltage 3 conversion result register of Device 1.
The CRC is computed in the AD7280A on Bits[D31:D10], that
is, the device address, the channel address, the conversion data,
and the write acknowledge bit. The calculated CRC is sent along
with Bits[D31:D10] and Bits[D1:D0] to the DSP/microprocessor.
The data received from the AD7280A is as follows:
1000 0001 0100 1100 1101 0101 0001 1000 (0x814CD518).
? Device address (read LSB first): 10000 (0x10)
? Channel address: 0010 (0x2)
? Conversion data: 100110011010 (0x99A)
? Write acknowledge: 1 (0x1)
? CRC: 01000110 (0x46)
? Reserved 0s: 0 (0x0)
The CRC bits are computed again in the DSP/microprocessor
on Bits[D31:D10] of the data that is read back from the
AD7280A. The data input to the CRC algorithm is, therefore,
1000000101001100110101 (0x205335).
Following the completion of the calculation, the value of
CRC_7 to CRC_0 is 01000110 (0x46). This result matches
the CRC that was sent from the AD7280A; therefore, this
transmission of data is valid.
CRC_7 to CRC_0 is 10011010 (0x9A). This result matches
the CRC that was sent from the AD7280A; therefore, this
transmission of data is valid.
