Programmable
Address
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.
