CCS/BQ76PL455EVM: tms57004 launchpad

Part Number:BQ76PL455EVM

Tool/software: Code Composer Studio

Hi,

I am using BQ76PL455EVM and TMS570 launchpad for cell 16 lithium ion cell balancing, voltage monitoring, temperature monitoring and communication monitoring.

i have made a following connection of SW1 and SW2:

1. SW1: 1 - up; 2,3,4 - down

2. SW2: 1 - on(towards diff side); 2 - off (towards Single side)

Also, I have removed R8 from TMS board. I have connected the serial port pins as shown in the sample code document.

I am using the sample code provided for communicating TMS570 launchpad and BQ76PL455EVM. I have imported, build and loaded the code in CCSv7 on the launchpad.

please find the snippet of code:

 // Clear all faults
    nSent = WriteReg(0, 82, 0xFFC0, 2, FRMWRT_ALL_NR);// clear all fault summary flags
    nSent = WriteReg(0, 81, 0x38, 1, FRMWRT_ALL_NR); // clear fault flags in the system status register

The registers 81 and 82 are allocated in BQ76PL455EVM.

1. How can I access these register values in CCSv7 to check whether this register is written or not ?

Thanks
