Configurable Logic Cell Tips ’n Tricks
TIPS ‘N TRICKS INTRODUCTION
Microchip continues to provide innovative products that
are smaller, faster, easier to use and more reliable.
Flash-based PIC
®
microcontrollers (MCUs) are used in
a wide range of everyday products from smoke
detectors to industrial, automotive and medical
products.
The PIC16(L)F150X and PIC10(L)F32X families of
devices with on-chip configurable logic cells merge all
the advantages of the PIC
®
MCU architecture and the
flexibility of Flash program memory with the functional-
ity of a configurable digital logic cell. Together, they
form a low-cost building block with resource savings
and external component reduction.
The flexibility of Flash and an excellent development
tool suite, including a low-cost In-Circuit Debugger, In-
Circuit Serial Programming
TM
(ICSP
TM
) and CLC
Configuration Tool GUI, make these devices ideal for
just about any embedded control application.
The following series of Tips ‘n Tricks can be applied to
a variety of applications to help make the most of digital
logic functions using a PIC MCU with on-chip
configurable logic.
CLC OVERVIEW
Input Selection
For all CLC modules, there are eight signals available
as inputs to the configurable logic cell, and these eight
input signals may vary from device to device. Neverthe-
less, only four can be selected at any one time. This is
done via four 8-input multiplexers, used to pass the
input signals on to the data gating stage of the CLC.
Input signals are selected with the CLCxSEL0 and
CLCxSEL1 registers, as shown in Figure 1.
