4.7.1.3.1 XC8 Linker - Runtime options

Initialize data

This checkbox controls whether initialized C objects are assigned their starting value. See 4.6.12 Mapped Linker Options.

Keep generated startup.as

This checkbox controls whether the runtime startup module is retained after compilation. See 4.6.1.13 Keep Startup Option.

Do not link startup module in

This checkbox controls whether the runtime startup module linked into the program. See 4.6.11.6 Nostartfiles Option.

Calibrate oscillator

This checkbox controls whether the oscillator calibration constant is applied by runtime startup module linked into the program. Not all devices uses this calibration method. See 4.6.1.15 Osccal Option.

Alternate oscillator calibration value

This field allows you to specify an alternate oscillator calibration constant to that preprogrammed into the device. Not all devices uses this calibration method. See 4.6.1.16 Oscval Option.

Backup reset condition flags

This checkbox controls whether the runtime startup code will preserve the state of the status register, so that it can later be examined to determine the cause of Reset. This option is not implemented for PIC18 device. See 4.6.1.19 Resetbits Option.

Format hex file for download

This checkbox controls the special formatting of the final HEX file. See 4.6.1.8 Download Option.

Managed stack

This checkbox controls whether a table look-up method of calling functions will be employed. See 4.6.1.24 Stackcall Option.

Program the device with default config words

This checkbox controls whether unspecified configuration bits will be programmed with default values. See 4.6.1.4 Config Option.

Link in C library

This selector controls the inclusion and language standard of libraries linked into the program. This utilizes the -mc90lib option (see 4.6.11.2 c90lib Option) and the -nodefaultlibs option, see 4.6.11.5 Nodefaultlibs Option.
