SIGNAL DESCRIPTIONS
A.1 FUNCTIONAL GROUPINGS OF SIGNALS
Table A-1 lists the signals for the 87C196CB, grouped by function. A diagram of each package
that is currently available shows the pin location of each signal.
NOTE
As new packages are supported, they will be added to the datasheets first. If
your package type is not shown in this appendix, refer to the latest datasheet to
find the pin locations.
