TMS320F28377D: about the CMP register

Green Deng

Part Number: TMS320F28377D

1、About the ePWM module of F28377D, whether the CMP register can be written as 0 or PRD?

2、During the period of initialization, CTRMODE=2, LOADBMODE=2, LOADAMODE=2, PHSEN=1, TBPHS=0, PHSDIR=1. Will the register load the value of CMP after carrier synchronization and TBCNT=0?

3、If it will, and the value is 0, What will happen?

Hi Green Deng,

1) You can write the CMP values as 0 or PRD.

2) This will depend on the value of LOADASYNC and LOADBSYNC. Take a look at Figure 14-4 Detailed View of the Counter-Compare Submodule ( http://www.ti.com/lit/ug/spruhm8f/spruhm8f.pdf )

3) The action programmed in the Action Qualifier submodule should be carried out.
