UARTPARERR
The linear component (LIN) of the clock rate as seen in the equation: rate = 24MHz / ( 2 * (LIN +
1) * (2^EXP) )
This bit is set when the transmit FIFO is empty and the transmitter is idle.
This bit is set when the receive FIFO has seen a parity error. This bit clears when the data
register (
This bit is set when the receive FIFO has seen a frame error. This bit clears when the data
register (
This bit is set when the receive FIFO has been overrun. This bit clears when the data register
(
This bit is set when the transmit FIFO is ready to accept at least one byte.
This bit is set when the receive FIFO contains at least one byte.
This bit shows the current state of the nCTS input signal at the nCTS pin (pin 19, GPIO11). When

TTL logic 1, GPIO is high, 'XOFF', RS232 negative voltage), transmission is inhibited at the end of
the current character. Any characters in the transmit buffer will remain there.
