The auto-CTS function reduces interrupts to the host system. When flow control is
enabled, a CTS1 state change does not trigger host interrupts because the device
automatically controls its own transmitter. Without Auto-CTS, the transmitter sends any
data present in the transmit FIFO and a receiver overrun error can result.
illustrates the Auto-CTS functional timing.
While starting transmission of the initial character the CTS1 signal is asserted.
Transmission will stall as soon as the pending transmission has completed. The UART will
continue transmitting a 1 bit as long as CTS1 is de-asserted (high). As soon as CTS1 gets
de-asserted transmission resumes and a start bit is sent followed by the data bits of the
next character.
The U1LSR is a read-only register that provides status information on the UART1 TX and
RX blocks.

U1LSR[0] is set when the U1RBR holds an unread character and is cleared when
the UART1 RBR FIFO is empty.
The UART1 receiver FIFO is empty.
The UART1 receiver FIFO is not empty.
The overrun error condition is set as soon as it occurs. An U1LSR read clears
U1LSR[1]. U1LSR[1] is set when UART1 RSR has a new character assembled
and the UART1 RBR FIFO is full. In this case, the UART1 RBR FIFO will not be
overwritten and the character in the UART1 RSR will be lost.
Overrun error status is inactive.
Overrun error status is active.
When the parity bit of a received character is in the wrong state, a parity error
occurs. An U1LSR read clears U1LSR[2]. Time of parity error detection is
dependent on U1FCR[0].
Note: A parity error is associated with the character at the top of the UART1 RBR
FIFO.
Parity error status is inactive.
Parity error status is active.
