Remark
Set UARTBn-related registers
INTUBnTIRE interrupt = 1?
INTUBnTITO interrupt = 1?
UBnRXE = 1 (UBnCTL0)
UBnRXE = 0 (UBnCTL0)
Check UBnFIS0 register
Read receive FIFO
Reception ended?

START
Read as many receive data as the number set as the trigger by the UBnFIC2.UBnRT3 to
UBnFIC2.UBnRT0 bits from receive FIFO in the pending mode (UBnFIC0.UBnIRM bit = 0). In the
pointer mode (UBnIRM bit = 1), reference the UBnFIS0.UBnRB4 to UBnFIS0.UBnRB0 bits and
read as many data as the number of bytes stored in receive FIFO from receive FIFO.
Read as many data (remaining receive data less than the number set as the trigger) as the
number of bytes stored in receive FIFO from receive FIFO by referencing the UBnFIS0.UBnRB4 to
UBnFIS0.UBnRB0 bits.
