Field Bits Size Volatile? Synopsis Type
DEST_MSK [7:0] 8 — Watchpoint destination mask RW
Operation
When read
When written
HARD reset
Defines which bits in the DEST_VAL field must match for the
watchpoint to trigger.
A value of ‘1’ in a bit position causes the watchpoint comparator to
ignore the corresponding bit of the DEST_VAL field, a value of ‘0’ in
a bit position causes the watchpoint comparator include the bit in
the comparison.
Thus, a value of 0xFF causes the destination field in each
transaction to be ignored and the watchpoint will match all
destinations.
It is an implementation specific property as to whether the
destination comparator is implemented.
