PLA MMRs Interface
The PLA peripheral interface consists on 21 MMRs, as shown
Table 97. PLA MMRs
Name
Description
PLAELMx
Element 0 to Element 15 Control Registers.
Configure the input and output mux of each
element, select the function in the look-up table,
and bypass/use the flip-flop.
PLACLK
Clock Selection for the Flip-Flops of Block 0 and
Clock Selection for the Flip-Flops of Block 1.
PLAIRQ
Enable IRQ0 and/or IRQ1. Select the source of the IRQ.
PLAADC
PLA Source from ADC Start Conversion Signal.
PLADIN
Data Input MMR for PLA.
PLAOUT
Data Output MMR for PLA. This register is always
updated.
A PLA tool is provided in the development system to easily
configure the PLA.
