Writes to the FIFO Single Byte Register write a single byte value to the command FIFO. If the command FIFO is full, the APB write operation is stalled until the command FIFO is not full.
Reads from the Single Byte FIFO Register read a single byte value from the command FIFO. If the command FIFO is empty, the APB read operation is stalled until the command FIFO is not empty.
See the ARM documentation for a description of the read and write values.
The name of this register in ARM documentation is BWFIFO1 for writes and BRFIFO1 for reads.

WARNING: The C register and register group struct declarations are provided for convenience and illustrative purposes. They should, however, be used with caution as the C language standard provides no guarantees about the alignment or atomicity of device memory accesses. The recommended practice for writing hardware drivers is to use the SoCAL access macros and alt_read_word() and alt_write_word() functions.
