The question of CY8CMBR3108 configuration

[tazh_4781221]

I am debugging a CY8CMBR3108 Capsense chip , using STM8S MCU to write data to the register of CY8CMBR3108 chip through IIC to configure the CY8CMBR3108 chip.Now I have encountered such a question. The STM8S MCU and the CY8CMBR3108 chip can read and write data normally through IIC. After writing data to  registers of the CY8CMBR3108 chip, I found that the chip could not be configured at all.I use my own code to configure the chip instead of the functions in the API in the official data manual.Will it matter?

The attachment is a detailed interactive information of IIC captured by logic analyzer when using ez-click 2.0 + miniprog3 to configure cy8cmbr3116 development board, that is, IIC configuration process of mbr3xxx chip. You can compare your configuration process with the standard process. I suspect that you did not perform the final configuration save action, so the configuration was not saved.
