16f690 CPU configuration

Each attribute in the configuration table below has two or more possible values associated with it.

e.g. the watchdog attribute (labelled field H ) has the possible values

one and only one of these values must be specified when configuring the CPU

The 16f690 CPU has 9 configuration attributes (labelled field A to I in the table below). The attributes specific to the 16f690 CPU are defined in the file hwreg-p16f690.h To correctly configure the 16f690 CPU each attribute must be set to a valid value. This is done by using one "pragma cpu_config" statement per attribute. A valid configuration for 16f690 would look like: 

e.g.
	include "hwreg-p16f690.h"

	pragma cpu_config CFG_FCMEN_ON
	pragma cpu_config CFG_IESO_ON
	pragma cpu_config CFG_BOR_ON
	pragma cpu_config CFG_CPD_ON
	pragma cpu_config CFG_CP_ON
	pragma cpu_config CFG_MCLRE_ON
	pragma cpu_config CFG_PWRTE_ON
	pragma cpu_config CFG_WDT_ON
	pragma cpu_config CFG_LP_OSC

NOTE: All attributes for a given processor must be specified, attributes for different processors may not be mixed.
