The VIMS module contains two FLASH line buffers because the FLASH word size is 128 bits.
The objectives of the buffers are to prevent refetching the 32-bit part of the data that has already been fetched (but not used) in a previous cycle. The status of the line buffers can be found in the VIMS:STATUS.IDCODE_LB_DIS register and the VIMS:STATUS.SYSBUS_LB_DIS register.
