Processor Configuration Registers
2.18.29 FRCDL_REG—Fault Recording Low Register
This register records fault information when primary fault logging is active. Hardware
reports the number and location of fault recording registers through the Capability
register. This register is relevant only for primary fault logging.
This register is sticky and can be cleared only through power good reset or by software
clearing the RW1C fields by writing a 1.

Fault Info (FI)
When the Fault Reason (FR) field indicates one of the DMA-
remapping fault conditions, bits 63:12 of this field contain the page
address in the faulted DMA request. Hardware treats bits 63:N as
reserved (0), where N is the maximum guest address width
(MGAW) supported.
When the Fault Reason (FR) field indicates one of the interrupt-
remapping fault conditions, bits 63:48 of this field indicate the
interrupt_index computed for the faulted interrupt request, and
bits 47:12 are cleared.
This field is relevant only when the F bit is set.
