14.7.2  AUTO-CTS 

 
The Auto-CTS function is enabled when CTSEN=1. If Auto-CTS is enabled, the transmitter circuitry checks the  UCTS 
input before sending the next data byte. When  UCTS is active (low), the transmitter sends the next byte. To stop the 
transmitter  from  sending  the  following  byte,  UCTS  must  be  released  before  the  middle  of  the  last  stop  bit  that  is 
currently being sent. In Auto-CTS mode, a change of the UCTS signal does not trigger a modem status interrupt unless 
the CTS Interrupt Enable bit is set, but the DCTS bit in the 

USARTn_MS

 register will be set.

The  Auto-CTS  function  typically  eliminates  the  need  for  CTS  interrupts. When  flow  control  is  enabled,  a  UCTS  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.

During transmission of the second character the UCTS signal is negated. The third character is not sent thereafter. The 
USART maintains 1 on UTXD as long as UCTS is negated (high). As soon as UCTS is asserted, transmission resumes 
and a start bit is sent followed by the data bits of the next character. 
 
 

14.8 AUTO-BAUD FLOW 

14.8.1  AUTO-BAUD

 

The  USART  auto-

baud function can be used to measure the incoming baud rate based on the “AT” protocol (Hayes 

command).  If  enabled  the  auto-baud  feature  will  measure  the  bit  time  of  the  receive  data  stream  and  set  the  divisor 
latch registers 

USARTn_DLM

 and 

USARTn_DLL

 accordingly. 

 
Auto-baud function is started by setting the START bit in 

USARTn_ABCTRL

 register, and can be stopped by clearing 

the  START  bit.  The  START  bit  will  clear  once  auto-baud  has  finished  and  reading  the  bit  will  return  the  status  of 
auto-baud  (pending/finished). When  auto-baud  function  is  started, FIFO  will  be  cleared,  not  available  to  write the  TX 
FIFO, and the transmitter will stop transmitting until auto-baud function finishes or be stopped. 
 
Two auto-baud measuring modes are available which can be selected by the MODE bit in 

USARTn_ABCTRL

 register. 

In Mode 0 the  baud rate  is measured on two subsequent falling edges  of the USART RX pin (the falling edge of the 
start bit and the falling edge of the least significant bit). In Mode 1 the baud rate  is measured between the falling edge 
and the subsequent rising edge of the USART RX pin (the length of the start bit).   
 
The AUTORESTART bit in 

USARTn_ABCTRL

 register can be used to automatically restart baud rate measurement if a 

timeout occurs (the rate measurement counter overflows). If this bit is set, the rate measurement will restart at the next 
falling edge of the URXD pin. 
 
The auto-baud function can generate two interrupts. 

 

 

The ABTOINT interrupt in 

USARTn_II

 register  will  get set if the interrupt is enabled (ABTOIE bit in 

USARTn_IE

 

register is set and the auto-baud rate measurement counter overflows).
