Question:

What is the recommendation for terminal setting of unused GPIO pins?

Notes:

1.This KBA applies to the following series of Traveo MCUs:

S6J3110

S6J3120

S6J3200

S6J3300

S6J3350

S6J3360

S6J3370

CY9D560

2.Product prefix "MB" has been changed to "CY".

Answer:

Leaving unused input pins open may cause permanent damage from a malfunction or latch-up. Take measures for unused pins such as pulling up or pulling down the voltage with resistors of 2 kilo ohms or higher.

If there are any unused input/output pins, set them to the output state and then open them, or set them to the input state and handle them in the same way as input pins.
