CHAPTER 15 ASYNCHRONOUS SERIAL INTERFACE B (UARTB)
(8) Receive operation in FIFO mode (pointer mode specified)
If the pointer mode is specified in the FIFO mode and if as many data as the number of bytes stored in
receive FIFO are read by referencing the UBFIS0 register, no data may be stored in receive FIFO
(UBFIS0.UBRB4 to UBFIS0.UBRB0 bits = 00000) even though the reception end interrupt request signal
(INTUBTIR) has occurred. In this case, do not read data from receive FIFO. Be sure to read data from
receive FIFO after confirming that the number of bytes stored in receive FIFO = 1 byte or more (UBRB4 to
UBRB0 bits = other than 00000).
