I am using the STM32F103RB chip but cannot find any implementation specific information for the AFSR register in the reference manual. Can anyone tell me where this register is specified?

This is probably a question for ARM but maybe someone knows the answer to it. Why are there two fault address registers, MMFAR and BFAR, at two different addresses when they are acually only one register internally?

Dear John,

You can refer to Our STM32 programming Manual PM0056

http://www.st.com/mcu/familiesdocs-110.html#Programming Manual

Cheers,

STOne-32.

Checked both the PM0056 and PM0008 manuals and so far not found much. The PM0056 does not mention the register at all (assuming that it is called the AFSR as indicated by the ARM docs).

So unfortunately the mystery remains unsolved! Is it possible that the register has not been implemented for this device?

Regards John
