TC9204M
Preliminary Data Sheet
9
Physical Layer Configuration / Polling
TC9204M embeds a Physical Layer MII Management configuration / polling entity which provides speed,
duplex, link status and link partner full duplex flow control ability information to the switch. This
information is obtained by continuously polling the status of Physical Layer devices through the serial
management interface. The entity is under control of EEPROM settings and it can operate in four
different modes. The polling entity also performs Phy configuration procedure at two seconds after reset
and each time EEPROM control information changes.
The following operating modes are available per port basis (selectable by
ANMode
field from EEPROM's
ConfigRegP[x]
):
00
–
Normal Mode
(assumed by default when EEPROM is not present):
Auto-Negotiation Enable bit from MII Control Register (0.12) is checked first. If it is found enabled
then TC9204M will disable advertisement for 1000BASE-T half duplex technology (9.8) and will
advertise the full duplex flow control ability (4.10:11) according with internal flow control enable
settings. Auto-negotiation is restarted leaving unchanged the rest of technology advertisements.
Then Auto-Negotiation Advertisement register (4), Link Partner Base Page Ability register (5) and
GMII registers (9:10) are polled continuously at 2 seconds interval in order to execute highest
common denominator resolution. If auto-negotiation is disabled as reported by 0.12 then the
switch will configure itself using bits 0.13 and 0.8 of Control register, and will consider link partner
full duplex flow control capable. Gigabit speed will be disabled.
01
–
Advertise one mode:
Auto-Negotiation Enable is checked and if found to be disabled
TC9204M will attempt to enable it. If successful the switch will force the port’s speed and duplex
mode by advertising only the technology corresponding to the
Speed
and
Duplex
fields from
EEPROM's
ConfigRegP[x]
, otherwise bits 0.8 and 0.13 will be read for configuration and gigabit
speed will be disabled. Full duplex flow control ability is also advertised along with selected
technology and then auto-negotiation is restarted. An auto-negotiation register polling is executed
as in Normal Mode.
10
–
Advertise multiple modes:
This mode is similar with previous one except that it advertises
the technology corresponding to the forced mode and all lower position technologies, down to
10BASE-T half duplex.
11
–
Disable Auto-Negotiation:
When this mode is selected then auto-negotiation is disabled
by setting bit 0.12 to ‘0’ and the forced speed and duplex mode will be written to Configuration
Register, bits 0.13, 0.6 and 0.8. This mode is available only for 10/100 Mbps speed modes so bit
0.6 will always be written as ‘0’. Link partner will be considered full duplex flow control capable.
In addition to the force mode feature, the TC9204M internal speed and duplex can be chosen between
enforced ones (
Speed
and
Duplex
fields from EEPROM's
ConfigRegP[x]
) and polling results by means
of
ForceIntMode
configuration.
Independently of Phy configuration/polling operation mode the Link Status is also permanently monitored.
If a Physical device reports link failure via 1.2 status bit then TC9204M disables transmission on
associated port without holding any memory resources allocated for its transmission queues. The
reported Link Status can be forced to ‘1’ using
ForceLink
bit from the same
ConfigRegP[x]
register.
