DESCRIPTION

This file provides the isp060COTblInit() function which initialized the
call out section of the umimplemented integer instruction handler. This
handler is provided by Motorola. The call out section is used by the
exception handler to call function which are host operating system dependent.
The call out handles the host operating system depend functions RELATIVE to
the call out section top address.
