Output Section With Split Address Range

On an RL78 there is a section of flash (0x2000) that is mirrored into the RAM address space (0xF2000). Jump tables must be in the mirrored code space. This is all so that it can use near pointers instead of far pointers. The problem is that .text…

Pointer to a register on a 16 bit controller

How do you declare a pointer on a 16 bit Renesas RL78 microcontroller using IAR's EWB RL78 compiler to a register which has a 20 bit address? Ex: static int *ptr = (int *)0xF1000; The above does not work because pointers are 16 bit addresses.
