16.3.26 BT FIFO Valid Size Register 0 (BTFVSR0)
BTFVSR0 is one of the registers used to implement BT mode. BTFVSR0 indicates a valid data
size in the FIFO for host write transfer.
16.3.27 BT FIFO Valid Size Register 1 (BTFVSR1)
BTFVSR1 is one of the registers used to implement BT mode. BTFVSR1 indicates a valid data
size in the FIFO for host read transfer.

These bits indicate the number of valid bytes in the
FIFO (the number of bytes which the slave can read)
for host write transfer. When data is written from the
host, the value in BTFVSR0 is incremented by the
number of bytes that have been written to. Further,
when data is read from the slave, the value is
decremented by only the number of bytes that have
been read.
