Instruction Set Architecture—IP2022 User’s Manual 148 www.ubicom.com instruction  can  only  be  executed  from  program
RAM. For more information, see Section 3.7. Cycles: 1 Example: mov    w,#0x01;load W with 0x01
mov    addrx,w;copy W to ADDRX
mov    w,#0x83;load W with 0x83
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
fwrite ;write flash memory This  example  writes  the  16-bit  data  held  in  the
DATAH/DATAL  register  to  address  0x18380  in
program flash memory. First, ADDRX/ADDRH/ADDRL is loaded                                                                                        with
0x018380. Then,  DATAH/DATAL is  loaded from
0x1FE     and     0x1FF.     Finally,     the     fwrite
instruction   loads   program   flash   memory   from
DATAH/DATAL   with   the   data   that   came   from
registers 0x1FE and 0x1FF.
