Upon receiving a load signal the module will start shifting out a start bit followed by all databits (lsb first) followed by parity (if enabled) and one or tw
 
o stop bits. The shifting when the edge_enable signal is high for one clock cycle. Load should only be asserted when buffer_empty is high. Buffer_empty will g
 
o high at the start of the last stop bit and reloading before the next edge_enable will give continueous operation.
 
 
 
edge_enables are only required when buffer_empty is low and are ignored when it is high.
 
 
 
The stop_value may also be used to force a break condition
