(9) UARTBn FIFO status register 0 (UBnFIS0)
The UBnFIS0 register is valid in the FIFO mode (UBnFIC0.UBnMOD bit = 1). It is used to read the number of
bytes of the data stored in receive FIFO.
This register is read-only in 8-bit units.
Reset sets this register to 00H.
UBnFIS0
(n = 0, 1)
After reset: 00H
CHAPTER 16 ASYNCHRONOUS SERIAL INTERFACE B WITH FIFO (UARTBn)
UBnRB4
Indicates the number of bytes (readable bytes) of the data stored in receive FIFO
as a receive FIFO pointer.
