Notes

The position and size of the supported config identifiers should be defined. This enables the identifiers to be used in #pragma config statements in an application.

   #pragma config_def [=] value

  value:
  0x0001:  FOSC in bit 0,1   : 0 - 3, LP, XT, HS, RC
  0x0002:  FOSC in bit 0,1,2 : 0 - 7, LP, XT, HS
  0x0004:  FOSC in bit 0     : 0, 1
  0x0008:  FOSC in bit 0,1,4 : 0 - 7, LP, XT, HS

  0x0010:  WDTE in bit 2: off (0), on (1)
  0x0020:  WDTE in bit 3: off (0), on (1)

  0x0100:  PWRTE in bit 3 (inverted):     on (0), off (1)
  0x0200:  PWRTE in bit 4 (inverted):     on (0), off (1)
  0x0400:  PWRTE in bit 3 (not inverted): off (0), on (1)

  0x1000:  BODEN in bit 6  : off (0), on (1)

Example: #pragma config_def 0x1111 // 0x0001 | 0x0010 | 0x0100 | 0x1000

   FOSC in position 0,1
   WDTE in position 2
   PWRTE in position 3 (0=on)
   BODEN in position 6

NOTE: THIS PRAGMA IS NORMALLY FOUND IN THE CHIP HEADER FILE AND

     SHOULD NOT BE USED IN THE APPLICATION SOURCE CODE.
