Lpc2000

Hey guys, I've started working with the LPC2138. I'm still working 
through the docs, but one question I have is this:

PLLCFG  = (4 + (2 << 5));
   E3A0320E   mov r3, #0xE0000000
   E283397F   add r3, r3, #0x001FC000
   E2833084   add r3, r3, #0x00000084
   E3A02044   mov r2, #0x00000044
   E5C32000   strb r2, [r3]

I'm using CrossWorks with a Olimex JTAG (works great so far BTW) with 
optimization turned off.

ARM assembly still isn't clear to me yet, so this is probably buried in 
the technical docs somewhere.

Why doesn't this compile to something like:

mov r3, #0xE01FC084
mov r2, #0x00000044
strb r2, [r3]

Can't the ARM load a 32 bit immediate?

Thanks,

Brian
