X Indexed addressing mode #reg[Rn] (reg = 0–255, n = 0–15)
XS Indexed (short offset) addressing mode #addr[RRp] (addr = range –128 to +127, where
p = 0, 2, ..., 14)

p = 0, 2, ..., 14)
da Direct addressing mode addr (addr = range 0–8191)
ra Relative addressing mode addr (addr = number in the range +127 to –128 that is
an offset relative to the address of the next instruction)
