Instruction Set Architecture—IP2022 User’s Manual 166 www.ubicom.com Example: mov    w,#0x00;load W with 0x00
mov    addrx,w;copy W to ADDRX
mov    w,#0x03;load W with 0x03
mov    addrh,w;copy W to ADDRH
mov    w,#0x80;load W with 0x80
mov    addrl,w;copy W to ADDRL
mov    w,0x1FE;copy 0x1FE to W
mov    datal,w;copy W to DATAL
mov    w,0x1FF;copy 0x1FF to W
mov    datah,w;copy W to DATAH
iwrite ;write program RAM This    example    writes    the    contents    of    the
DATAH/DATAL  register  to  address  0x000380  in
program RAM. First,                                                                                         the
ADDRX/ADDRH/ADDRL  register  is  loaded  with
0x000380.  Then,  the  DATAH/DATAL  register  is
loaded   from   0x1FE   and   0x1FF.   Finally,   the iwrite  instruction  loads  program  RAM  from DATAH/DATAL.
