multipal serial ports

[Darrel Taylor]

SERIN2 can use even parity.

But since it can't transmit at the same time it's receiving,
it'll be a whole lot easier with USART's

İf you want to communicate many chip.You will use RS485 protocol.But when device send data dont able to recive data at same time.
