The FSR (Firmware State Register) can be found at offset 0 in the SRAM and it is holding information about the state of the ROM/FW. In case of a boot failure it can be used to get the state where the boot process got stuck, it does not itself contains error codes as such.
The error code (or the firmware state information) is stored in the next soft register at offset 0x4.
