The ROM library is placed at the addresses specified in the associated prm file,
EERAMfuncsIRQ.prm, listed below:
The RAM functions defined within code segment RAM_FUNCTIONS are
placed in section RAM_FUNCS. This is located at the RAM address at which
the functions will be copied to and executed from, this section must have the
attribute READ_ONLY. The addresses allocated for the RAM functions may
need to be expanded, depending on the size of the interrupt service routines
and if EECALLBACK is defined.
The structure containing the Flash control registers is placed in the section
FLASH_REGS which is located at the default address. If the registers are
remapped after reset then this address will have to be changed. This section
must have the attribute NO_INIT.
This example uses the timer module, so the structure containing the timer
control registers is placed in the section TIMER_REGS at the default address.
The pre-defined segments DEFAULT_RAM and DEFAULT_ROM are listed to
comply with the linker, although they contain no data or code.
Finally, all the RAM function names and interrupt service routines that are
executed from RAM and are not explicitly called must be listed under the
ENTRIES command.
