NOTE 1
When a change of serial speed is requested, the values of the S214 and S217 registers are automatically set to
a value greater than or equal to the period of three characters at the speed requested (13 ms for 2400 bauds, 7
ms for 4800, otherwise 3 ms)
NOTE 2
Transmission mode without flow control. Please note that using a serial transmission rate that is higher than the
radio transmission rate will of necessity lead to the loss of characters in the absence of flow control.
If the radio transmission rate is equal to the serial transmission rate, the radio frame is longer than the serial
frame due to the header required by the radio protocol; but the radio header will only be generated at the start of
the radio transmission and this header will be absorbed by the size of the internal buffer.
For example, if the current radio transmission rate is 10 kbits/s, a serial transmission rate of 9600 must be used
without flow control, while a serial transmission rate of 19,200 (with 10 kbits/s for the radio transmission rate) will
produce a data overflow.
In order to prevent loss of characters, you should:
• use flow control (addressed mode with hardware handshake).
• or use a serial transmission rate less than or equal to the radio transmission rate.
• or limit the size of the serial data to the maximum size of the internal buffer (S218).
