Auto-CTS Functional Timing
9.5.9 UART Line Status Register

bits0..7
The auto-CTS function reduces interrupts to the host system. When flow control is
enabled, a CTS 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 CTS 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 CTS is deasserted (high). As soon as CTS gets
deasserted transmission resumes and a start bit is sent followed by the data bits of the
next character.
The LSR is a Read Only register that provides status information on the UART TX and RX
blocks.

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