Reinitialization Sequence
The MAX1455 provides for reestablishing, or relearning,
the baud rate. The reinitialization sequence is a 1-byte
transmission of FFhex, as follows:
When a serial reinitialization sequence is received, the
receive logic resets itself to its power-up state and
waits for the initialization sequence. The initialization
sequence must follow the reinitialization sequence in
order to reestablish the baud rate.
