TMS470R1B1M, CAN module

I am trying to configure the CAN module (HECC1)
Steps followed are:
1. Entering the configuration mode by instruction

pHECC1->CANMC = CCR + ABO;


2.Waiting until CPU has access to CAN configuration registers

3.setting the baudrate register as below

pHECC1->CANBTC = (13 << 16) + SAM + TSEG1_14 + TSEG2_2 + SJW_1;


The value is not getting reflected in memory area of BTC registor (i.e. 0xFFF7E82C).

because of this i am not able to come out of configuration mode.

Pls let me know wheres the mistak

Deepak
