void ser485Tx(void);
Enables the RS-485 transmitter. Transmitted data get echo'ed back into the receive data buffer. These
echo'ed data could be used to know when to disable the transmitter by using one of the following
methods:
Byte mode—disable the transmitter after the same byte that is transmitted is detected in the receive
data buffer.
Block data mode—disable the transmitter after the same number of bytes transmitted is detected in the
receive data buffer.
serMode() must be executed before running this function.

void ser485Rx(void);
Disables the RS-485 transmitter. This puts the LP3500 in listen mode, which allows it to receive data
from the RS-485 interface. serMode() must be executed before running this function.
