A.1.5. Flow Control(FC_CTRL) On/Off Signal
If user wants to set the status of hardware flow control option using AT+UARTCONFIG command,
FC_CTRL signal should be connected with UART_CTS signal.
If Hwfc parameter in AT+UARTCONFIG command is set to 1, FC_CTRL signal is set to high and then
hardware flow control is enabled. And if Hwfc parameter in AT+UARTCONFIG command is set to 0,
FC_CTRL signal is set to low and then hardware flow control is disabled.
A.1.6. Bluetooth Status LED(STATUS_LED0, STATUS_LED1) Signal
 If any Bluetooth device is connected, this signal is set to high during 150msec periodically
after low status during 1 sec.
 When the connection status is Standby, this signal is set to high.
 When the connection status is Pending, this signal is toggled 3 times periodically after low
status during 1 sec.
 When the connection status is Connect, this signal is set to low.
A.1.7. Reset Signal
Parani-BCDx10 can be reset from one of following sources:
- RESETB pin
- Power on reset
- UART break character
- Software configured watchdog timer
The RESETB pin is an active low signal and is internally filtered using the internal low frequency clock
oscillator. A reset will be performed between 1.5 and 4.0ms following RESETB being active. So it is
recommended that RESETB be applied for a period greater than 5ms.
