;; The following is the required magic for NCD to like the image
br start
.int 0,0,1 /* 1 is for ignoring CRC16 */
string "Xncd19C\000"
.int 0 /* CRC16 value would go here */
start: or.u r2, r0, hi16(L1)
or.u r3, r0, hi16(0x04013F6C)
or r3, r3, lo16(0x04013F6C)

jmp.n r3
or r2, r2, lo16(L1)
L1:
ascii "hello world\nhello Joanna.\n\000"
