*1) I : Input, O : Output, I/O : Input/Output, I/O (PD) : Input/Output with Pull-down Register, O (TS) : Tri-State Output.
*2) All card slot interface signal names are pretended with A-(slot#0) and B-(slot#1).
For example, ACA25 to ACA0 are the card address buses to the slot#0.
Pin No. of the RB5C396 differ from those of others. Refer to “PIN CONFIGURATION”.
