Interfacing 433MHz RF Module with PIC16F688

I am trying to interface the RF module which comes with Transmitter (FS1000A) and Receiver (MX-RM-5V) in pairs and interfacing with 2 sets of the circuit consists of 2 PIC16F688. After sourcing the internet, it seems like it can be interfaced either digital I/O or UART but I'm not sure about this. Is this possible to connect both of RF module in the following manner:

Transmitter side: Transmitter (FS1000A) - PIC1 (TX) [Not sure about the RX of PIC pin should be floating, grounded, shorted...
