Testing the parity mechanism can be done by enabling the bit RamDirectAccess (DCAN_TEST[9] RDA) and manually writing the parity bits directly to the dedicated RAM locations. With this, data and parity bits could be checked when reading directly from RAM.
If parity check is disabled, the software has to ensure correct parity bit handling in order to prevent parity errors later on when parity check is enabled.
