Pin type abbreviation: A = Analog, D = Digital, I = Input, O = Output.
1.2 Configuring the RN4677 1.4 Control and Indication I/O Pins
Configuring the RN4677 features are performed using The configurable control and indication I/O pins are either RN-style ASCII command documented in the P00, P05, P17, P31, P32, P33, P34 and P37. The “RN4677 Bluetooth® Low Energy Dual Mode Module RN4677 uses control signal as the input, whereas User’s Guide”. Alternatively, it is possible to configure indication signals are the output. Table 1-3 shows the RN4677 using the interface as described in configurable I/O pin assignments to the control and

, along with either external PC
Note:
RTS is only assigned to P00 and CTS to configuration utility (UI Tool or EEPROM Tool), or the PIC MCU configuration library. For more information, P17. visit www.microchip.com/rn4677.

Pin Name Default Configuration
The RN4677 UART pins TXD and RXD connect to the P00 UART_RTS UART pins of the host MCU. It is highly recommended to use hardware flow control pins RTS and CTS. By P05 NO_USE default, the RN4677 hardware flow control is disabled P17 UART_CTS and must be configured to become enabled. The UART P31 INQUIRY_CONFIGURE Baud is configurable and the available signal rates are P32 LINK_DROP listed in Table 4-5. P33 UART_RX_IND P34 PAIRING_KEY P37 LOW_BATTERY_IND DS50002370A-page 6
