C Compiler

Reference Manual

June 2010

OVERVIEW

PCB, PCM and PCH Overview

The PCB, PCM, and PCH are separate compilers. PCB is for 12-bit opcodes, PCM is for 14-bit

®

opcodes, and PCH is for 16-bit opcode PIC microcontrollers. Due to many similarities, all three

compilers are covered in this reference manual. Features and limitations that apply to only specific

microcontrollers are indicated within. These compilers are specifically designed to meet the unique

needs of the PIC® microcontroller. This allows developers to quickly design applications software

in a more readable, high-level language.

When compared to a more traditional C compiler, PCB, PCM, and PCH have some limitations. As

®

an example of the limitations, function recursion is not allowed. This is due to the fact that the PIC

has no stack to push variables onto, and also because of the way the compilers optimize the code.

The compilers can efficiently implement normal C constructs, input/output operations, and bit

twiddling operations. All normal C data types are supported along with pointers to constant arrays,

fixed point decimal, and arrays of bits.
