ARM DDI0198D
Fault address register (FAR)
For load and store instructions that can involve the transfer of more than one word
(LDM/STM, LDRD, STRD, and STC/LDC), the value written into the FAR register
depends on the type of access, and for external aborts, on whether or not the access
crosses a 1KB boundary. Table 3-10 shows the FAR values for multi-word transfers.
Compatibility Issues
To enable code to be easily ported to ARM architecture v4 or v5 MMUs, or to future
architectures, it is recommended that no reliance is made on external abort behavior.
The instruction FSR is intended for debugging purposes only. Code that is intended to
be ported to other ARM architecture v4 or v5 MMUs must not use the instruction FSR.
