MAC Core Signals
2-3
2.1.1 Transmit Function to Host Signals
Below is a list of the signals between the E-110 MAC transmit function
and the host transmit buffer. All signals are active HIGH unless otherwise
noted. All signals are synchronous with the rising edge of the MII PHY
transmit clock (MTXC). Signal direction is with respect to the transmit
function block. See the Section 3.2.1.1, “MAC Transmit Function,” on
page 3-5 for further details on transmit buffer and transmit function
interaction.
TPAB
Transmit Packet Abort
When asserted, the TPAB signal indicates that the trans-
mission was discontinued. TPAB remains asserted until
the E-110 MAC function receives a request to transmit,
which is indicated when the MAC control module asserts
TPSF. When deasserted, TPAB indicates that the trans-
mission was not aborted. The following circumstances
cause the transmission to be halted:
Excess deferrals which occur when the media is busy
longer than twice the maximum frame length (greater
than 24,288
1
bits when the HUGEN signal is deas-
serted or greater than 524,288
2
bits when HUGEN is
asserted)
Late collision (use RTRYL to avoid aborting)
Multiple collisions (greater than 15)
Transmit underrun
Larger than normal packet, which is 1518 bytes (see
also see the HUGEN signal description)
Output
The TPAB signal is also connected to the optional MAC
control module core.
TPD[7:0]
Transmit Packet Data
The TPD[7:0] signals are the transmit data bus. The host
must hold the TPD[7:0] signals valid for exactly two
MTXC clock cycles.
Input
1. 24,288 bits = 1518 bytes x 8 bits/byte x 2 (242.88
μ
s for 100-Mbit/s operation or 2.4288 ms
for 10-Mbit/s operation)
2. 524,288 bits = 32 Kbytes x 8 bits/byte x 2 (5242.88
μ
s for 100-Mbit/s operation or 52.43 ms
for 10-Mbit/s operation)
