4.11.6
There are TWO ethernet ports on the M68360QUADS-040 implemented via SCC1 and SCC2 of the
QUICC.
The first Ethernet port is implemented by connecting SCC1 to Motorola’s MC68160 EEST device. The
MC68160 provides two Ethernet interfaces: AUI (P3) and Twisted-Pair (P4). The connection between the
MC68160 and the QUICC is straight forward, and does not require external glue logic.
case however, only AUI port is implemented via P5.
To support other uses of SCC2, it’s signals are available also at the expansion connectors and the SIA
(U4) is mounted on a socket. That way the SIA can be removed freeing SCC2 signals for other use via the
expansion connector - P11.
4.11.6.1
The AUI port connectors P3 and P5 are 15 pin, female, D-type connectors as shown in FIGURE 2-6.
The list below describes the port signals. The directions ’I’, ’O’, and ’I/O’ are relative to the M68360QUADS-
040 board. (I.E. ’I’ means input to the M68360QUADS-040)
The second Ethernet port is implemented by connecting SCC2 to AMD’s SIA (Am7992) device. In this

SIMM4 to SIMM1 - These four bits, encode the data identifying the DRAM SIMM connected to the
M68360QUADS-040. For the various DRAM types supported, refer to TABLE 4-1.
BKINT* - When active ’0’, indicates that the last level 7 interrupt (NMI) was generated by the
Hardware Breakpoint logic.
OPT0* - When active ’1’, indicates that switch #5 in DSW1 is in ON position
OPT1* - When active ’1’, indicates that switch #4 in DSW1 is in ON position
OPT2* - When active ’1’, indicates that switch #3 in DSW1 is in ON position
