Notes: 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. Bcc is the general name for conditional branch instructions.

3. Cannot be used in this LSI.

4. Only register ER0, ER1, ER4, or ER5 should be used when using the TAS instruction.
