Signals
E110_MTXC
E-110 Transmit Clock
Input
In 10/100 mode, E110_MTXC is the clock input from the
E-110. The frequency is 25 MHz or 2.5 MHz, depending
on the mode of operation. The transmit interface logic in
the E-1110 core operates using this clock.
E110_MRXC
E-110 Receive Clock
Input
In 10/100 mode, E110_MRXC is the clock input from the
E-110. The frequency is 25 MHz or 2.5 MHz, depending
on the mode of operation. The receive interface logic in
the E-1110 core operates using this clock.
3.6 Scan Signals
The signals in this section are used for E-1110 testing. Signal direction
is from the perspective of the E-1110 core.
TEST_SO
Test Scan Out
Output
The TEST_SO is a serial scan chain output pin.
TEST_MODE
ATPG Test Mode Enable
Input
When TEST_MODE is asserted, the MAC enters the test
mode.
TEST_SE
Test Scan Enable
Input
When TEST_SE is asserted, all the internal ip-ops
accept data on the TEST_SI input pin.
TEST_SI
Test Scan In
Input
TEST_SI is a serial scan chain input pin.
3.7 Gigabit PCS Interface Signals
The signals in this section are used to interface the E-1110 core to the
external PCS. Signal direction is from the perspective of the E-1110 core.
PCS_GMII_TCLK
PCS GMII 125 MHz Transmit Clock
Output
See the denition for E1110_MII_TCLK.
