CRAM error checking ability (32-bit CRC)
during user mode, for use by the
CRC_ERROR pin.
There is only one 32-bit CRC value, and
this value covers all the CRAM data.

This section focuses on the first type—the 32-bit CRC when the device is in user
mode.
There are two sets of 32-bit registers in the error detection circuitry that store the
computed CRC signature and pre-calculated CRC value. A non-zero value on the
signature register causes the CRC_ERROR pin to set high.

32-bit registers: the signature register and the storage register.

16-bit CRC embedded in every configuration data frame.
During configuration, after a frame of data is loaded into the device, the
pre-computed CRC is shifted into the CRC circuitry.
Simultaneously, the CRC value for the data frame shifted-in is calculated.
If the pre-computed CRC and calculated CRC values do not match,
nSTATUS is set low.
Every data frame has a 16-bit CRC. Therefore, there are many 16-bit CRC
values for the whole configuration bit stream.
Every device has a different length of configuration data frame.
