CCS/TMS320F28027: How to disable the watchpoit Register once it is configured

Part Number:TMS320F28027

Tool/software: Code Composer Studio

Currently we are configuring watch point register for few address location in the stack to monitor the stack and it is working. Now, we need to disable this configured watch point and configure for new address range. The above mentioned steps shall go on in for loop as with application. For us, we are able to get the RTOS interrupt when someone is writing in monitored address location and we are not sure how to disable the configured watch point and get configure for new address range.
