13 Errata

CRC computation may not be reliable when the GPIO is configured as an input. This is because the GPIO input status is a runtime value that can change dynamically. When the touch configuration is saved, the CRC is calculated using the Touch Configuration along with the current GPIO input status. If the GPIO input status changes before the CRC is validated on the host side, a CRC mismatch will occur. Therefore, using CRC for configuration validation is not effective when the GPIO is set as an input, as the input value may vary between the time of CRC calculation and validation.

Workaround

Do not use the CRC when any of the GPIOs is configured as an input.
