8.13 Transmitter FIFO Level register (TXLVL)
This register is a read-only register. It reports the number of spaces available in the
transmit FIFO.
8.14 Receiver FIFO Level register (RXLVL)
This register is a read-only register, it reports the fill level of the receive FIFO, that is, the
number of characters in the RX FIFO.
8.15 Programmable I/O pins Direction register (IODir)
This register is used to program the I/O pins direction. Bit 0 to bit 7 controls GPIO0 to
GPIO7.
8.16 Programmable I/O pins State register (IOState)
When ‘read’, this register returns the actual state of all I/O pins. When ‘write’, each
register bit will be transferred to the corresponding I/O pin programmed as output.
