Signal Descriptions
asserted, TPSF is asserted one clock after HST_TPSF is
asserted for a data or a control packet transmit request.
When FLOWCON_EN is deasserted, TPSF is asserted
at the same clock as when HST_TPSF is asserted for a
data packet request. The MAC control module does not
interpret the transmit data in any way and transmit data
is routed from the host to the E-110 MAC directly.
TRST_L
Transmit Reset
Other modules in an ASIC can use the TRST_L signal as
a host reset synchronized to the transmit clock (MTXC).
Because the MTXC clock can be slow with respect to a
host reset pulse, or even stopped, the host reset signal
(HRST_L) is captured in the E-110 MAC transmit func-
tion. The transmit function asserts TRST_L asynchro-
nously to MTXC when the HRST_L signal occurs and
deasserts TRST_L synchronously on the positive transi-
tion of MTXC. Modules can use TRST_L to initialize
transmit logic. The TRST_L signal is also connected to
the host.
Output
2.1.4 MII to PHY Signals
The signals that interface the MAC MII to the PHY (not including the
MIIM interface) are listed below. All signals are active HIGH. Signal
direction is with respect to the MAC MII function. See IEEE 802.3u
standard documentation for further information. The standard IEEE MII
signal name references are shown in brackets.
MCOL
Collision Detected
The PHY asserts the MCOL [COL] signal asynchronously
with minimum delay from the start of a collision on the
media. The PHY deasserts MCOL to indicate no collision.
MCOL is internally synchronized to the MTXC clock and
in the worst case may take up to two clock cycles to be
detected by the MAC transmit function.
Input
MCRS
Carrier Sense
The PHY asserts the MCRS [CRS] signal asynchro-
nously with minimum propagation delay from the detec-
tion of a non-idle medium. The PHY deasserts MCRS
when it detects an idle medium. The PHY also asserts
MCRS with minimum propagation delay in response to
MTXEN [TX_EN].
