TC9204M
Preliminary Data Sheet
determined by EEPROM configuration (default is IP). If no header is found or corresponding
prioritizations are disabled then port based prioritization is executed. When EEPROM is present an
additional method of prioritization is available. This method consists of selecting the highest service class
from all classes corresponding to the enabled prioritization sources (IP, VLAN and port based). For both
methods, when no prioritization source is available the default CoS is used (default is normal priority –
CoS1 but it can be also changed by EEPROM configuration).
The CoS features can be configured by adjusting shared configuration pins and/or programming
EEPROM Register settings. VLAN prioritization can be enabled by
EnVLPr
shared configuration pin or
by EEPROM register settings, while
EnIPPr
shared configuration pin or the EEPROM Register settings
can enable IP prioritization. The shared configuration pins are sampled during reset.
The per-port basis CoS can be set using
PriClass [x][1:0]
shared configuration pins or configuring
EEPROM registers, where
x
stands for port number. The port-based prioritization can be disabled from
EEPROM settings only.

PriClass[x][1:0] TxDataX_[1:0]
Set the priority class per port basis
'00' – the port has class 0 priority(lowest priority)
'01' – the port has class 1 priority
'10' – the port has class 2 priority
'11' – the port has class 3 priority(highest priority)
EnIPPr
Enable/disable IP prioritization
‘0’ – IP priority within the received packet (if exists) is ignored
‘1’ – IP priority within the received packet (if exists) is considered
EnVLPr
Enable/disable VLAN prioritization
‘0’ – VLAN priority within the received packet (if exists) is ignored
‘1’ – VLAN priority within the received packet (if exists) is considered
