PA2, PB2 - RS232 Ports’ Connectors

The RS232 ports’ connectors - PA2 and PB2 are 9 pin, 90o, female D-Type Stacked connectors,

signals of which are presented in TABLE 5-2. "PA2, PB2 Interconnect Signals" below

5•1•3

P3 - Ethernet Port Connector

The Ethernet connector on the MPC8XXFADS - P3, is a Twisted-Pair (10-Base-T) compatible con-

nector. Use is done with 90o, 8-pin, RJ45 connector, signals of which are described in TABLE 5-3.

"P3 - Ethernet Port Interconnect Signals" below.

20 - 25

GND

Ground.

Not connected with this application

27 - 29

HOST_VCC

HOST VCC input from the host. Used to qualify FADS selection by the host. When host

is off, the debug port controller is disabled.

HOST_ENABLE~

HOST Enable input signal from the host. (Active low). Indicates that the host computer

is connected to FADS. Used, in conjunction with HOST_VCC and ADS_SEL(2:0) to

qualify FADS selection by the host.

31 - 33

GND

Ground.

PD0

Bit 0 of the ADI port data bus

PD2

Bit 2 of the ADI port data bus

PD4

Bit 4 of the ADI port data bus

PD6

Bit 6 of the ADI port data bus
