3.1 UART
Four signals are used to implement the UART function. UART_TXD and
UART_RXD transfer data between the two devices. The remaining two signals,
UART_CTS and UART_RTS, can be used to implement RS232 hardware flow
control where both are active low indicators.
3.1.1 UART S etting
User can change data format the following selection using PSKEY. However, host shall communicate with
default setting UART connection initiated at first time.
Baud Rate = (PS K EY _UART _BAUD_RAT E) / 0.004096
Parameter
Possible value
Baud Rate
9600 ~ 3M Baud
Flow Control
RTS/CTS or None
Parity
None, Odd or Even
Number of Stop Bits

3.1.2 UART Bypass Mode
Switch the bypass to PIO[7:4] as shown in figure. When the bypass mode has been invoked, module
enters the deep sleep state indefinitely.
