Put one letter (Y, N) in each BOX from proposed for the column.
For Pull-Up/Down if “Y” add also one letter (S,W) to define type of resistor. (see
*1 When used as N-channel Open drain output not-controlled Pull-Up (Y-SOD) can be used. Pull Up active during Output also
*2 Port-wise for PortC and PortD (one possibility for the whole port); PortB bit-wise

At higher V
Put in each box one of 3 possibilities mentioned in the title of column like 18n, 24p (strongest configuration). Numbers
above state for number of active N and P transistors in output buffer. See electrical parameters to know what to expect at
different option. Important Note: Maximum V
terminals can switch at the same time in strongest configuration to limit the spikes generated by switching.

if Y-S is set in Pull-Up & Y for Nch-open drain an external resistor is needed to make output High !!!! because Pull Up is active
during input only ! This is applicable only for Ports B,C,D and E which can be outputs also.
