5.2.8 MR7 –Next Page Transmit Register Bit Descriptions
FIELD
TYPE
7.15 (NEXT_PAGE)
R/W
Next Page.
This bit indicates whether or not this is the last next page to be
transmitted. When this bit is 0, it indicates that this is the last page. When
this bit is 1, it indicates there is an additional next page.
7.14 (ACK)
R
Acknowledge.
This bit is the acknowledge bit from the link code word.
7.13 (MESSAGE)
R/W
Message Page.
This bit is used to differentiate a message page from an
unformatted page. When this bit is 0, it indicates an unformatted page.
When this bit is 1, it indicates a formatted page.
7.12 (ACK2)
R/W
Acknowledge 2.
This bit is used by the next page function to indicate that a
device has the ability to comply with the message. It is set as follows:
When this bit is 0, it indicates the device cannot comply with the message.
When this bit is 1, it indicates the device will comply with the message.
7.11 (TOGGLE)
R
Toggle.
This bit is used by the arbitration function to ensure
synchronization with the link partner during next page exchange. This bit
will always take the opposite value of the toggle bit in the previously
exchanged link code word:
If the bit is logic 0, the previous value of the transmitted link code word was
logic 1.
If the bit is a 1, the previous value of the transmitted link code word was a 0.
The initial value of the toggle bit in the first next page transmitted is the
inverse of the value of bit 11 in the base link code word, and may assume a
value of 1 or 0.
7.10:0 (MCF)
R/W
Message/Unformatted Code Field.
With these 11 bits, there are 2048
possible messages. Message code field definitions are described in annex
28C of the IEEE 802.3u standard.
DESCRIPTION
5.2.9 MR16 – PCS Control Register Bit Descriptions
FIELD
TYPE
16.15 (LOCKED)
R
Locked.
Locked pin from descrambler block.
16.14-12 (UNUSED)
R
Unused.
Will always be read back as 0.
16.11-4 (TESTBITS)
R/W
Generic Test Bits.
These bits have no effect on the PCS block. They are for
external use only. A 0 should be written to these bits.
16.3 (LOOPBACK)
R/W
Loopback Configure.
When this bit is high, the entire loopback is
performed in the PCS macro. When this bit is low, only the collision pin is
disabled in loopback.
16.2 (SCAN)
R/W
Scan Test Mode
.
16.1
(FORCE
LOOPBACK)
or disabling the collision pin.
16.0 (SPEEDUP
COUNTERS)
(Same as FASTTEST = 1.)
DESCRIPTION
R/W
Force Loopback.
Force a loopback without forcing idle on the transmit side
R/W
Speedup Counters.
Reduce link monitor counter to 10 us from 620 us.
