PROGRAMMABLE LOGIC ARRAY (PLA)
Every ADuC7019/20/21/22/24/25/26/27/28/29 integrates a
fully programmable logic array (PLA) that consists of two
independent but interconnected PLA blocks. Each block
consists of eight PLA elements, giving each part a total of
16 PLA elements.
Each PLA element contains a two-input lookup table that can
be configured to generate any logic output function based on
two inputs and a flip-flop. This is represented in Figure 76.

Figure 76. PLA Element
In total, 30 GPIO pins are available on each ADuC7019/20/21/
22/24/25/26/27/28/29 for the PLA. These include 16 input pins
and 14 output pins, which msut be configured in the GPxCON
register as PLA pins before using the PLA. Note that the
comparator output is also included as one of the 16 input pins.
The PLA is configured via a set of user MMRs. The output(s) of
the PLA can be routed to the internal interrupt system, to the
CONVSTART signal of the ADC, to an MMR, or to any of the 16
PLA output pins.
The two blocks can be interconnected as follows:
Output of Element 15 (Block 1) can be fed back to Input 0
of Mux 0 of Element 0 (Block 0).
Output of Element 7 (Block 0) can be fed back to the Input 0
of Mux 0 of Element 8 (Block 1).

PLAELMx are Element 0 to Element 15 control registers. They
configure the input and output mux of each element, select the
function in the lookup table, and bypass/use the flip-flop. See
Table 147 and Table 152.
