The Boot module supports boot initialization for the MSP430 devices. A special boot init function is created based on the configuration settings for this module. This function is hooked into the xdc.runtime.Reset.fxns[] array and is called very early at boot time (prior to C runtime initialization).

The code to support the boot module is placed in a separate section named ".text:bootCodeSection" to allow placement of this section in the linker .cmd file if necessary. This section is a subsection of the ".text" section so this code will be placed into the .text section unless explicitly placed, either through Program.sectMap or through a linker command file.
