      Table 3.9
      Subroutine background_code_lode
      cl_status is set:
      by subroutine
      background_code_load
      CLS_SUCCESS
      if the memory write over the TWS bus was
      successful.
      CLS_FAILURE_NVM
      if the memory write over the TWS bus fails.
      CLS_FAILURE_CHECKSUM
      if the checksum over the data in code_buffer
      fails.
      CLS_FAILURE_ADDRESS
      if the byte count plus the address exceed the
      maximum image length (measured for the
      inactive image).
      Table 3.10
      Subroutine do_code_load
      cl_addr is set:
      by subroutine
      do_code_load
      CLS_BUSY
      if a valid Mode 4 Write Buffer command with
      CDB[3] = 0 (load new data into external
      memory), 0xFD (set the flag to update the
      EEPROM) or 0xFE (set the flag to force a soft
      Reboot (See notes on Register 0xFE00).
      Note: The function
      background_code_load
      will disable interrupts and trip the watchdog
      timer by using an infinite loop.
      CLS_IDLE
      if a valid Mode 4 Write Buffer command with
      CDB[3] = 0xFF.
      1. Note:
      cl_status
      is initialized (by
      init_stuff
      ) to the value CLS_IDLE
      2. Note: Mode 4 Write Buffer SCSI transfers require the code load status
      variable (
      cl_status
      ) be in the idle state (CLS_IDLE). Attempts to perform
      SCSI transfers when the system is not idle result in a check condition.
