Expansion Port Connectors
Two expansion port connectors (
P2
and
P3
) provide access to the
ADSP-2181 processor’s bus signals, letting you watch data transmissions.
The
P2
and
P3
connectors are sites for 50-pin header connectors. In addi-
tion, the host interface, interrupt, and
PWM_EVENT
pins are also available on
this connector
#
External port loading can effect external bus speed and
performance.
