• Section 2—Data Operations
– How to organize data in memory to use parallel moves
– How to use the barrel shifter in various applications
– The benefit and use of the 16-bit Arithmetic support
– Some examples that show the benefit of few of the new
arithmetic and logical instructions
• Section 3—Program Control
– How to use the on-chip hardware stack
– Benefit and usage of the Stack Extension
– Usage of the conditional arithmetic and logical
instructions
– How to use the PC relative instructions for code
relocation and saving of program words
