Choosing the host baud rate

The calculation of the UART baud rate from the length of the first 0 byte that is received, allows the 
operation of the boot loader with a wide range of baud rates. However, to ensure proper data transfer, the 
upper and lower limits have to be kept.

SCI autobaud rate feature operates by polling the LINFlex_RX pin for a low signal. The length of time 
until the next low to high transition is measured using the System Timer Module (STM) time base. This 
high-low-high transition is expected to be a zero byte: a start bit (low) followed by eight data bits (low) 
followed by a stop bit (high). 

Upon reception of a zero byte and configuration of the baud rate, an acknowledge byte is returned to the 
host using the selected baud rate.

Time base is enabled at reception of first low bit, disabled and read at reception of next high bit. Error 
introduced due to polling will be small (typically < 6 cycles).

The following equation gives the relation between baud rate and LINFlex register configuration:

Eqn. 33-1

LDIV is an unsigned fixed point number and its mantissa is coded into 13 bits of the LINFlex’s register 
LINIBRR. 

From this equation and considering that a single UART transmission contains 9 bits, it is possible to obtain 
the connection between time base measured by STM and LINIBB register:

Eqn. 33-2

To minimize errors in baud rate, a large external oscillator frequency value and low baud rate signal are 
preferred.

Example 33-3. Baud rate calculation for 24 kBaud signal

Considering a 24 kbaud signal and the device operating with 20 MHz external frequency.

Over 9 bits the STM will measure: (9 × 20 MHz)/24 kbaud = 7497 cycles. 

Error expected to be approximately ± 6 cycles due to polling.

Thus, LINIBB will be set to 52 (rounding required). This results in a baud rate of 24.038 kbaud. Error of 
< 0.2%. 

To maintain the maximum deviation between host and calculated baud rate, recommendations for the user 
are listed
