Error Registers
This section describes the registers that record the first and next errors, logging,
detection masks, signalling masks, and error injection control. The FERR_GLOBAL (first
error register) is used to record the first error condition. The NERR_GLOBAL register is
used to record subsequent errors.
The contents of FERR_GLOBAL and NERR_GLOBAL are “sticky” across a reset (while
PWRGOOD remains asserted). This provides the ability for firmware to perform
diagnostics across reboots. Note that only the contents of FERR_GLOBAL affects the
update of the any error log registers.
FERR_GLOBAL - Global First Error Register
The first fatal and/or first non-fatal errors are flagged in the FERR_GLOBAL register,
subsequent errors are indicated in the NERR_GLOBAL register.
NERR_GLOBAL - Global Next Error Register
Once an error has been logged in the FERR_GLOBAL, subsequent errors are logged in
the NERR_GLOBAL register.
