Hi Cesar, You have to enable the diagnostics by setting DIAG_EN bit. Once enabled the AFE does the checks and gives the output on Flags as well as on LED_ALM and PD-ALM pins. So you can observes those pins or read the flags ( register 0x30) after 8mS of enabling DIAG_EN. For further details, please refer to section 8.4.3 of datasheet. Regards, Prabin.
