LINK Core Control Register Higher Rank
This register controls the functions of the LINK core.
Bit7 Pass Self-ID Packet
Setting this bit to "1" captures a Self-ID packet received by the LINK core into the buffer.
Bit6 Pass PHY Packet
When requesting the PHY Register for a register write, this bit is set to "1". After the execution, this bit is
cleared.
Bit5 Pass BusReset Packet
Setting this bit to "1" captures a BusReset packet received by the LINK core into the buffer.
Bit4 Enable Posted Block Write
Setting this bit to "1" enables the Posted Write function for a Block Write Request.
Bit3 Enable Posted Quadlet Write
Setting this bit to "1" enables the Posted Write function for a Quadlet Write Request.
Bit2 APHY
Indicates whether the PHY conforms to 1394.a or not.
1: Conforms to PHY 1394.a
0: Does not conform to PHY 1394.a
Bit1 Enable Ack Acceleration
Indicates the setting of Ack Acceleration.
1: Ack Acceleration enable
0: Ack Acceleration disable
Bit0 cmstr
When the self node is Cycle Master capable and a root, this bit becomes "1".
If the self node does not become a root in the Self-ID processing when this bit is set after the Bus Reset, this
bit is cleared.
