Other Parts Discussed in Thread: RCV420

When I was welding RCV420 on the circuit board, due to an operation error, the sixth pin of the chip was connected to the ground (the sixth pin is NC pin).The pin was suspended, but now it's grounded.Will this affect the circuit?Is the sixth pin of RCV420 connected to the circuit inside the chip?Please help me, thank you.
