4.4 CRC Computing Result XOR Value Register
The CRC computing result XOR value register (PRGCRC_FXOR) specifies the value of XOR (exclusive
OR) for final results of CRC computing.
Register configuration
Register functions
[bit31:0] PRGCRC_FXOR (CRC Final XOR value)
Sets the value of XOR (exclusive OR) for final results of CRC computing.
Reads the register setting value.
When the bit value of PRGCRC_FXOR is "1", the value of the corresponding bit of PRGCRC_RD is
inverted. The bit value is "0", is not inverted. The value of PRGCRC_FXOR is applied to the value after
output format conversion.
Table 4-4 shows an example setting of PRGCRC_FXOR when all CRC computing results are inverted.
Table 4-4 Example setting of PRGCRC_FXOR when all CRC computing results are inverted
PRGCRC_FXOR setting value
Set 0x0000 0000 for PRGCRC_FXOR if all CRC computing results are not inverted.
Write access to this register is not allowed when CRC computing is performed
(PRGCRC_CFG.LOCK="1").
