After the synch field is received, the next state will wait for the start bit of the
next field, the identifier field. After the start bit is detected using the input
capture functionality, all the eight bits representing the ID must be received.
This process is performed in the RECEIVING_DATA state.
After the start bit is detected, the timer is configured to overflow on every
bit-time to capture all eight bits as shown in
