Notes: B: Byte size; W: Word size; L: Longword size.

1. POP.W Rn and PUSH.W Rn are identical to MOV.W @SP+, Rn and MOV.W Rn, @-

SP. POP.L ERn and PUSH.L ERn are identical to MOV.L @SP+, ERn and MOV.L ERn,

@-SP.

2. B is the general name for conditional branch instructions.

CC

3. Cannot be used in this LSI.

4. When using the TAS instruction, use registers ER0, ER1, ER4, and ER5.

5. ER7 is not used as the register that can be saved (STM)/restored (LDM) when using

STM/LDM instruction, because ER7 is the stack pointer.
