How to configure the registers for watchdog window settings without any communication.

Thread Summary

The user inquires about configuring watchdog registers (WDCDIV, WDCFG) on the MAX20478, noting the absence of communication ports like SPI or I2C. The final answer states that the MAX20478 is covered by an NDA, and support must be sought through the Customer Interaction Center (CIC) via phone, as public forum support is not available.

According to the 'Watchdog Window Settings' of the data sheet, watchdog clock rate and two window lengths can be configured by setting registers related to watchdog (ex) WDCDIV, WDCFG.

I have two questions.

1. There is no communication ports like SPI or I2C in the circuit / Diagram of MAX20478. How to configure the registers I said above. (Is it impossible to set the registers in MAX20478 by user?)

2. Where can I get the information about the registers of MAX20478? I just have the datasheet which has 11 pages.
