Description
R
Contents of ASI_AFAR_D1. This field has the following two functions:
• Indicates the type of error held in the other fields of ASI_AFAR_D1 as
defined in
TABLE P-15
• Controls the recording of newly detected restrainable errors. Upon
detection of a new restrainable error recordable in ASI_AFAR_D1, if the
current ASI_AFAR_D1.CONTENTS < the AFSR
error, the new error is recorded into ASI_AFAR_D1. If the current
ASI_AFAR_D1.CONTENTS
error is not recorded into ASI_AFAR_D1 and ASI_AFAR_D1 is unchanged.
R
D1 cache way with the error. Indicates the D1 cache way number (0 or 1) in
which the error is detected.
I
R
ndicates the virtual address bits 15:13 contained in the D1 cache index of the
cache line that caused the error. Because the D1 cache is a VIPT cache, the D1
cache index contains the virtual address bits 15:13.
R
Indicates the physical address bits 42:6 for the D1 cache line that caused the
error.
R
Always reads as 0.
W
Any write access sets all fields in this register to 0. That is, when a program
writes to ASI_AFAR_D1, the entire ASI_AFAR_D1 is set to 0 regardless of the
write value; the error in ASI_AFAR_D1 is expunged.

Hard POR: All fields in ASI_AFAR_D1 are set to 0.
Other reset: Value in ASI_AFAR_D1 is unchanged.
When a new restrainable error is detected, ASI_AFAR_D1 is
updated as defined in Section P.7.1 in the notes on the AFSR
Prio_D1 column of
When program writes to ASI_AFAR_D1, all fields in
ASI_AFAR_D1 are set to 0 and validated.
