    Decoder (PAD)
    The PSD3XX contains two programmable arrays, referred to as PAD A and PAD B
    (Figure 4). PAD A is used to generate chip select signals derived from the input address to
    the internal EPROM blocks, SRAM, I/O ports, and Track Mode signals.
    PAD B outputs to Ports B and C for off-chip usage. PAD B can also be used to extend the
    decoding to select external devices or as a random logic replacement.
    PAD A and PAD B receive the same inputs. The PAD logic is configured by PSDsoft
    based on the designer’s input. The PAD’s non-volatile configuration is stored in a
    re-programmable CMOS EPROM. Windowed packages are available for erasure by the
    user. See Table 4 for a list of PAD A and PAD B functions.
