CCS/TMS570LS3137: N2HET Instruction Set - Control Word

Part Number: TMS570LS3137

Tool/software: Code Composer Studio

Hi Team,

As per Technical Reference Manual Literature No: SPNU499B section 20.5.3 of N2HET module, most of the instructions mentioned have 29 to 31st bit of Control Word always as reserved(0).

But only for one instruction(20.5.3.3 ADCNST (Add Constant)) I noticed the reserved bits are 27 to 31st.

Can you please let me know if these bits in Control word are always expected to be reserved for all the instructions ?

Thanks for your help in advance.

Best regards,

Vivek Shetty
