Bits 15 to 13—Transmit FIFO Water Mark (TFWM2 to TFWM0): The transfer request of the
transmit FIFO is controlled by TDREQ bit of SISTR register. FIFO depth is always 16 steps,
nevertheless the setting to these bits.

Bits 7 to 5—Receive FIFO Water Mark (RFWM2 to RFWM0): The transfer request of the
receive FIFO is controlled by TDREQ bit of SISTR register. FIFO depth is always 16 steps,
nevertheless the setting to these bits.

Bits 12 to 8—Transmit FIFO Usable Area (TFUA4 to TFUA0): TFUA shows usable number
of words for CPU or DMAC to transfer from 00000 to 10000 (initial value).
Bits 4 to 0—Receive FIFO Usable Area (RFUA4 to RFUA0): RFUA shows usable number of
words for CPU or DMAC to transfer from 00000 (initial value) to 10000.
