12.4 PC Card Memory-Mode Enable Signals
12.5 PC Card Memory Mapping
PC Card memory-mode enable signals, nPC_CE1 and nPC_CE2, are output on pin MCELn
and pin MCEHn, respectively. Along with the address signal output on pin AD[0] and the data
signals input or output on pins DA[15:8] and DA[7:0], the nPC_CE1 and nPC_CE2 signals
specify the type of access that is being made to the particular segment of memory in the PC
Card, as shown in
The address mapping for access to an 8- or 16-bit PC Card is shown in
