Instruction Set Architecture—IP2022 User’s Manual 160 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
iread                          ;read program memory
mov    w,datal;move low byte to W
mov    0x1FE,w;copy W to 0x1FE
mov    w,datah;move high byte to W
mov    0x1FF,w;copy W to 0x1FF This   example   reads   a   word   stored   at   byte
address    0x000380    in    program    RAM.    First,
ADDRX/ADDRH/ADDRL is loaded                                                                                        with
0x000380.   After   the   iread   instruction,   the
DATAH/DATAL register holds the word read from
program RAM. Then, the lower byte of the word is
copied  to  data  memory location  0x1FE  and the
upper  byte  is  copied  to  data  memory  location
0x1FF.
