DEVICE CONFIGURATION
--------------------

PICmicro configuration information can be put in the generated hex
and assembly file. ID locations can also be programmed. The
configuration information is generated IF AND ONLY IF the #pragma
config statement is included.

Note that some PICmicro device programmers may reject this information.

Syntax:

    #pragma config[<offset>] = <expression>
    #pragma config[<offset>] |= <expression>
    #pragma config[<offset>] &= <expression>

    #pragma config ID[<offset>] = <expression>

Examples:

    #pragma config[0] = 0b.1.000.0101     // byte at address 0x300000
    #pragma config[1] |= 3                // set bit 0,1 (address 0x300001)
    #pragma config[2] &= ~0xF0, |= 0x80   // clear bit 4-7, set bit 7
    #pragma config[2+1] = 0xF | 0x80

    #pragma config ID[0] = 0x9            // byte at address 0x200000
    #pragma config ID[1] = 0x8            // byte at address 0x200001
    #pragma config ID[2] = 0x3


The CONFIG and ID are specified in BYTES.

CC8E will join 2 bytes into a 16 bit WORD in the generated hex, asm
and list files. If only one byte is defined for a word, then the
default value is used for the undefined byte. The default setting of
config attributes are 1. ID locations have 0 as default value.

It is also possible to define the CONFIG and ID locations by using
#pragma cdata statements. Then 16 bits words is defined directly.


CONFIG word start address:
    PIC18 : 0x300000

ID word start address:
    PIC18 : 0x200000
