(10) UARTBn FIFO status register 1 (UBnFIS1)
The UBnFIS1 register is valid in the FIFO mode (UBnFIC0.UBnMOD bit = 1). This register can be used to
read the number of empty bytes of transmit FIFO.
This register is read-only in 8-bit units.
Reset sets this register to 10H.
Caution The values of the UBnTB4 to UBnTB0 bits are reflected after transmit data has been written
UBnFIS1
(n = 0, 1)
After reset: 10H
to the UBnTX register and then time of two cycles of the peripheral clock (f
Therefore, care must be exercised when referencing the UBnFIS1 register after transmit
data has been written to the UBnTX register.
