Trigger RESETBMCU signal of PF0100 from I2C interface

We are using i.MX (Solo, DL, dual and quad) with PF0100 PMIC chip.

We would like to trigger the RESETBMCU signal from software, to ensure that hardware reset and SW reset behave in exactly the same way on our device (we use the signal as reset also for additional devices on our board).

Currently we use the internal watchdog to reset the CPU, but this does not tigger the signal on the PMIC.

The PMIC has an I2C interface, but checking the datasheet, I couldn't find a command/register bit that can trigger a reset or re-execute the power-up sequence.

Is it possible to trigger a reset/power-up sequence using the I2C interface?
