2.3 High Speed UART interface
JODY-W2 series modules support a high-speed Universal Asynchronous Receiver/Transmitter
(UART) interface in compliance with the industry standard 16550 specification.
The main features of the UART interface are:
 FIFO mode permanently selected for transmit and receive operations
 Automatic baud rate detection
 Two pins for transmit and receive operations
 Two flow control pins
 Interrupt triggers for low-power, high throughput operation
 High throughput (4 Mbps)
