Both? There are eight possible 2316 ROMs. There are three chip selects
each with active high/low prograrming options. The Apple ][(+) uses two
of those eight - the Rev 7 and later 2316 chargen is 2716 pinout
compatible while the Integer/Applesoft/OldMonitor/AutoStart chips are
all incompatible because of the choice Apple made to use pin 18 as an
active high enable line.

The 2532 has A11 (18), /E (20) & Vpp (21) so will not disable its
output when pin 18 is high.
