4/17/98 6-13 Addressing Modes and Data Types
Table 6.3 shows a summary of the basic addressing modes available for data transfer and
calculation related instructions.
Notes:
- Shift class includes rotates, shifts, and normalize.
- USP = User stack pointer.
* : ADDS and MOVS uses a short immediate field (4 bits).
** instructions with no operands include: BKPT, NOP, RESET, RET, RETI.
