What is the debounce time on CTRL_RESET_MICO#?

I see from the PCA9450 datasheet that this is selectable by I2C, but I have no idea if the default 50 ms is correct, or it is lengthened by software at some point.

PCA9450 datasheet, page 35, T_PMIC_RST_DEB.

I know that 24 ms is not enough! I wanted to stretch this out on our CPLD that drives that signal.

Thanks in advance.

The current version of the Linux driver for PCA9450 doesn’t implement a change to the default value of the T_PMIC_RST_DEB field. So, the debounce time on the CTRL_RESET_MICO# is set to 50ms.
