3.3 RESET Sequence
RESET is asserted by module itself, the external reset circuit is not required.
3.4 UART (Universal Asynchronous Receiver Transmitter)
UART_TxD, UART_RxD, UART_RTS, UART_CTS form a conventional asynchronous data serial
port. The interface is designed to operate correctly when connected to other UART devices such as
the NS16550A. The signaling levels are 0V and VCC. The interface is programmable over a variety
of bit rates; none, even or odd parity; one or two stop bits and hardware flow control on or off. The
default condition on power-up is pre-assigned in the Flash memory.
The maximum UART data rate is 1.3824 Mbps. Two-way hardware flow control is implemented by
UART_RTS and UART_CTS. UART_RTS is an output and is active low. UART_CTS is an input
and is active low. These signals operate according to normal industry convention.
