If the error output pin is in PWM mode then when no error is detected it will toggle according to programmable MMR widths for high and low periods. When an error occurs, the error pin stops toggling and remains constant until the error is cleared. An external PMIC that is detecting the PWM toggles can identify the error if the pin stops toggling. The periods should be programmed such that they fit within the expectation of the external PMIC.
