TMS320F28377S: About Indirect Addressing Modes.

Part Number: TMS320F28377S

Hi all,

I have a question in the description of the following trailing material.

http://software-dl.ti.com/trainingTTO/trainingTTO_public_sw/c28x28377/C28x_Microcontroller_MDW_6-1.pdf

I think that description of "AND *XAR2,#1234h" can not be done with C28x, is it correct? 

In the following manual, indirect addressing mode does not support "AND" instruction.

5.9 Program Space Indirect Addressing Modes(p.104)

Best regards,

Sasaki

    Hi Sasaki,

    This is a legal instruction for logical AND between a specified integer and a data memory location, identified by *XAR2.  The assembler should take it.  The instruction is shown on p.154 of the manual, where in our case "loc16" is determined by XAR2.  Are you experiencing any issues with this instruction?

    The chapter on p.104 refers to operations on program space.  Indirect addressing on data space begins on p.86. 

    Best regards,

    Richard

    I had overlooked it and checked it.
