Decode PLD (DPLD)
The DPLD

A product term indicates the logical OR of two or more inputs. For example, three product
terms in a DPLD output means the final output signal is capable of representing the logical
OR of three different input signals, each input signal representing the logical AND of a
combination of the 69 PLD inputs.
Using the signal FS0 for example, the user may create a 3-product term chip select signal
that is logic true when any one of three different address ranges are true... FS0 = address
range 1 OR address range 2 OR address range 3.
The phrase “one product term” is a bit misleading, but commonly used in this context. One
product term is the logical AND of two or more inputs, with no OR logic involved at all, such
as the CSIOP signal in
Eight Main Flash memory sector select signals (FS0-FS7) with three product terms
each
Four Secondary Flash memory sector select signals (CSBOOT0-CSBOOT3) with three
product terms each
One SRAM select signal (RS0) with two product terms
One select signal for the base address of 256 PSD module device control and status
registers (csiop) with one product term
Two external chip-select output signals for Port D pins, each with one product term (52-
pin devices only have one pin on Port D)
Two chip-select signals (PSEL0, PSEL1) used to enable the 8032 data bus repeater
function (Peripheral I/O mode) for Port A on 80-pin devices. Each has one product
term.
