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. Since register ER7 functions as the stack pointer in an STM/LDM instruction, it cannot
be used as an STM/LDM register.
3. Cannot be used in this LSI.
4. B
CC
is the general name for conditional branch instructions.
