fifosinglebyte
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.

Writes to the FIFO Double Byte Register write a double 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 Double
Byte FIFO Register read a double 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
