3.2.11
The yellow DMARUN indicator is connected to AS* signal of the slave QUICC, this to indicate bus activity
of one of the QUICC’s DMA channels.
3.2.12
The green LED Ethernet Transmit indicator blinks whenever the EEST is transmitting data through one of
the Ethernet ports P3 or P4.
3.2.13
The green LED Ethernet Receive indicator blinks whenever the EEST is receiving data from one of the
Ethernet ports P3 or P4.
3.2.14
The red LED Ethernet Collision indicator CLSN, blinks whenever a collision is detected in the AUI P3 port
or the TP P4 port, or a jabber condition is detected in TP mode.
3.2.15
The yellow LED Ethernet Twisted Pair Link Integrity indicator - LIL, lights to indicate good link integrity on
the TP P4 port. The LED is off when the link integrity fails, or when the AUI port is selected.
3.2.16
The red LED Ethernet TP Polarity indicator - PLR, lights if the wires connected to the receiver input of TP
P4 port are reversed. The LED is lit by the EEST, and remains on when the EEST has automatically
corrected for the reversed wires.
3.2.17
The red LED Ethernet TP Jabber indicator - JABB, lights whenever a jabber condition is detected on the
TP P4 port.
3.2.18
The yellow POWER indicator, indicates the presence of the +5V supply at P5.
3.3
At the beginning of each cycle, the chip-select generator of the slave QUICC determines the kind of
memory cycle and which device is selected. Cycle types and address spaces are determined for EC040
cycles by the Transfer Modifier lines TM0 - TM2 and the Transfer Type lines TT0 - TT1 and by Function
Codes FC0 - FC3 for QUICC’s DMA cycles. The cycle types and the devices that respond are described
in TABLE 3-1.
