This target is provided to build the final application with interrupts enabled
during programming and erasure.
The files EE_Emulation.c, VectorTable.c and main.c are compiled and linked
together with the ROM library generated in the "EE RAM functions with IRQs"
target, generating the absolute file EE_EmulationIRQ.abs.
The compiler directive "-DIRQ_DURING_PROG" is specified on the compiler
command line to activate the code required to enable interrupts to be serviced.
The linker directive "-AddEE_RAMfuncsIRQ.abs" is specified on the linker
command line to link in the previously generated ROM library.
The linker directive "-M" is specified on the linker command line so that a map
file is generated.
The application is linked to the addresses specified in the associated prm file,
EE_Emulation_IRQ.prm, listed below:
= NO_INIT
= NO_INIT
= READ_WRITE
= NO_INIT
= NO_INIT
= READ_ONLY
