Table 221: Receive MAC Programmable IPv6 Extension Header Register (0x6A0)
Bit Field Description Init Access
31 Programmable Extension
Header Type #2 Enable
This bit enables programmable extension header #2. If this bit
is clear, then the value programmed in bits [15:8] of this register
will be ignored. If this bit is set, then extension headers will be
checked for a type matching the value in bits [15:8]. This bit
should be set to 0 if IPv6 RX is disabled.
0R/W
30 Programmable Extension
Header Type #1 Enable
This bit enables programmable extension header #1. If this bit
is clear, then the value programmed in bits [7:0] of this register
will be ignored. If this bit is set, then extension headers will be
checked for a type matching the value in bits [7:0]. This bit
should be set to 0 if IPv6 RX is disabled.
0R/W
29:16 Reserved Reserved bits 0 RO
15:8 Programmable Extension
Header Type #2
These bits contain the programmable extension header value
for programmable header #2.
0R/W
7:0 Programmable Extension
Header Type #1
These bits contain the programmable extension header value
for programmable header #1.
