problem from disassembly for TI MSP430

Hi,

I am puzzling by what I observe from the disassembly from IAR for TI MSP430. I have the following codes:

ORG 0F000h xor.w #0xFF20,0x214

The disassembler will generate this (which is what I expect): xor.w #0xFF20,0x214

However, if I have this instead:

RSEG CODE xor.w #0xFF20,0x214

I will get this from the disassembler: xor.w #0xFF20,0xF214

Can someone pls tell me why I would have 0xF214 instead of 0x214?

Many thanks. feilip
