R/W
RO
The 7:0 part of the 24-bit word EXT_ADDR_EN that
enables / disables source address matching for each of
the 12 extended address table entries.
EXT_ADDR_EN[7:0]
Write access: Extended address enable for table entry n
(0 to 7) is mapped to EXT_ADDR_EN[2n]. All
EXT_ADDR_EN[2n + 1] bits are read only and don’t care
when written to.
Read access: Extended address enable for table entry n
(0 to 7) is mapped to both EXT_ADDR_EN[2n] and
EXT_ADDR_EN[2n+1].
Optional safety feature: To ensure that an entry in the
source matching table is not used while it is being
updated, set the corresponding EXT_ADDR_EN bit to 0
while updating.
