Direct Addressing Instructions
*: Place an NOP after the DMOV instruction that specifies R13+ as the transfer source.
(Note)
The assembler calculates and sets values in the dir8, dir9, and dir10 fields as follows:
dir8 -> dir, dir9/2 -> dir, dir10/4 -> dir dir 8, dir9, and dir10 are unsigned.

Resource Instructions
2) When label32-PC-2 is outside of the range in 1) and includes an external reference
symbol, an instruction is created as follows:
Bxcc false xcc: Counter condition of cc
LDI:32 #label32,Ri
JMP:D @Ri
false:
