Possible nRF52840 documentation defect on QDEC PIN.LED

[Phase]

In the nRF52840 Product Specification v1.1 (HTML), description of the QDEC peripheral, Table 77 on page 275 (direct content link), it appears to indicate that the LED pin for the QDEC peripheral must be set to Input.

However, reviewing the documentation, it appears that this pin is used to drive an LED (for optical encoders). Therefore, it would appear that this should instead be configured as an Output pin.

Here's a reproduction of the table, , which I've reproduced here:

QDEC signal	QDEC pin	Direction	Output value	Comments
Phase A	As specified in PSEL.A	Input	Not applicable
Phase B	As specified in PSEL.B	Input	Not applicable
LED	As specified in PSEL.LED	Input	Not applicable

Q: Can you confirm this is a defect in the documentation, and that the pin provided as QDEC's PSEL.LED must be configured as Output?

Update: This question also applies to the remaining nRF52 series' product specification documentation:

• nRF52832
• nRF52811
• nRF51810

Thus, if this is a documentation defect on the nRF52840, these other three product specifications are also likely to have the same defect.
