Description
Transmit Enable: Active high, synchronous to TXCLK; indicate that
the transmission data is valid.
Strap function during reset--
TXEN(7:0): 0 = port 7-0 full duplex
Transmit Clock: Provides the timing reference for the transfer of
TXEN, TXD signals. It is 25MHz for 100Mbps and 2.5MHz for
10Mbps.
Transmit data for port 0; synchronous to TXCLK0.
Strap function during reset--
TDX0[0]: 0=80Mhz, 1=66Mhz CLOCK operation
TXD0[1]: 0=enable partition mode, 1=disable partition mode
TXD0[2]: 0=enable expansion port, 1=disable expansion port
TXD0[3]: 0=init only, 1= enable BIST
Transmit data for port 1; synchronous to TXCLK1.
Strap function during reset --
TXD1[2:0]: test mode
TXD1[3]: 0=enable CRC, 1=disbale CRC
Transmit data for port 2; synchronous to TXCLK2.
Strap function during reset --
TXD2[2:0]: device # setting
TXD2[3]: DRAM timing 0=fast, 1=slow
Transmit data for port 3; synchronous to TXCLK3.
Strap function during reset --
TXD3[0]: 0=max. packet size 1536, 1=max. packet size 1518(default)
TXD3[1]: 0=enable back_pressure, 1= disable (default)
TXD3[3:2]: age strap pins
00= 64 sec. 01= 128 sec.
10= 256 sec. 11= disbale
Transmit data for port 4; synchronous to TXCLK4.
Strap function during reset –
TXD4[0]: 0= port 0 trunking enable 1= port 0 no trunking (default)
TXD4[1]: 0= port 1 trunking enable 1= port 1 no trunking (default)
TXD4[2]: 0= port 2 trunking enable 1= port 2 no trunking (default)
TXD4[3]: 0= port 3 trunking enable 1= port 3 no trunking (default)
Transmit data for port 5; synchronous to TXCLK5.
Strap function during reset –
TXD5[1:0]: broadcast filtering rate selection
00 = 8k/sec 01 = 16k/sec
10 = 64k/sec 11= disable
Transmit data for port 6; synchronous to TXCLK6.
Transmit data for port 7; synchronous to TXCLK7.
Receive data for port 0; synchronous to RXCLK0.
Receive data for port 1; synchronous to RXCLK1.
Receive data for port 2; synchronous to RXCLK2.
Receive data for port 3; synchronous to RXCLK3.
Receive data for port 4; synchronous to RXCLK4.
