number of bytes stored in receive FIFO can be read from receive FIFO by referencing the
UBnFIS0 register. In some cases, however, data is not stored in receive FIFO even though the
INTUBnTIR signal is generated (UBnFIS0.UBnRB4 to UBnFIS0.UBnRB0 bits = 00000). In these
cases, do not read data from receive FIFO. Always read data from receive FIFO when the number
of bytes stored in receive FIFO is 1 byte or more (UBnRB4 to UBnRB0 bits = other than 00000).
