AN983B PCI/miPCI Fast Ethernet Controller with integrated PHY
20~16 TBCNT Transmit Burst Count
0
R/W
After this number of consecutive successful transmit,
transmit completed interrupt will be generated.
Continuously do this function if no reset.
11~0 TTO
Transmit Time-Out = (deferred time + back-off time).
0
R/W
When the TDIE (bit28 of ACSR7) is set, the timer is decreased
in unit of 2.56us(100M) or 25.6us(10M). If the timer expires
before another packet transmit begin, then the TDIE
interrupt will be generated.
CSR24 (offset = a0h) - FROM, Flash ROM (also the boot ROM) port
Bit # Name Descriptions
Default Val RW Type
31
Bra16_on This bit is only effective while 4 LED mode selected (bit 23 of 1
R/W
CSR18 is set).
When 4 LED mode selected, and this bit is set, then pin 105
is defined as brA16, else it is defined as LED pin – fd/col.
