DESCRIPTION
J25.9 + J25.10
Reserved
Not Installed
—
This jumper is not for use with the
DS33Z44 design kit. Pin J25.10 has
been removed to prevent accidental
installation.
J25.7 + J25.8
Enable device driver
User decision
—
When installed the device driver will
configure the DS33Z44 and the
Transceiver during power-up.
J25.5 + J25.6
Enable callbacks
User decision
—
When installed the driver will
respond to interrupts.
