14.5.6 Capture Registers

The retry buffer and the capture registers are separate set of registers. The first read which hits the retry buffer causes the capture registers to be loaded.

The capture register will be locked (will not be updated) on the setting a SEC/DED interrupt flag and remain locked until the interrupt flag caused by the SEC/DED is cleared.

  • An SEC flag locks the registers for SECs until the flag is cleared but would accept a DED. In other words a subsequent double bit error will flush the captured single bit error and correction.
  • An DED flag locks the registers until the flag is cleared.
