In order for the OEM Host and a transceiver to communicate over the serial interface they need to have the same
serial data rate. This value determines the baud rate used for communicating over the serial interface to a transceiver.
For a baud rate to be valid, the calculated baud rate must be within ±3% of the OEM Host baud rate.

For baud rates other than those shown in Table 5 the following equations can be used:

Where:
FREQUENCY = 32 MHz
BAUD_M = EEPROM Address 0x43
BAUD_E = EEPROM Address 0x44

T a b l e 5 : B a u d R a t e / I n t e r f a c e T i m e o u t
