11.5.12 FIFO Transmit Start Register (TFSR)
The TFSR register,
transmit FIFO. Usually there is no need to program TFSR. For optimal RAM allocation, do not program
TFSR to a value less than its reset value. The value in this register must be added to MBAR + 0x800 to
determine the absolute address.
The TFSR register is reset to the first available RAM address.
