Question:

What is the side effect when the input cut off function is not released?

Answer:

The initial setting of the GPORTEN register, which is related to the input cut off function is "disable input". Even if it is not released, the external signal input such as a port input or an external interrupt cannot be transmitted to the internal circuit. Therefore, the disable input must be released for detecting an external signal.

This KBA applies to the following series of Traveo MCUs:

- S6J3110

- S6J3120

- S6J3200

- S6J3300

- S6J3350

- S6J3360

- S6J3370

- S6J3400

- S6J3510

- CY9D560

The prefix MB of the product has been changed to CY. For instance, MB9D5XX has been changed to CY9D5XX.
