30 / 98 page  Table 7-5. Summary of Interrupt Signals EVENT SAFE STATE INTERRUPT BIT INTERRUPT MASK STATUS BIT RECOVERY/INTERRUPT CLEAR Buck current limit triggered (20-µs debounce) No effect BUCK_INT = 1 BUCKx_ILIM_INT = 1 BUCKx_ILIM_MASK BUCKx_ILIM_STAT Write 1 to the BUCKx_ILIM_INT bit Interrupt is not cleared if the current limit is active. Boost current limit triggered No effect BOOST_INT = 1 BOOST_ILIM_INT = 1 BOOST_ILIM_MASK BOOST_ILIM_STAT Write 1 to the BOOST_ILIM_INT bit. Interrupt is not cleared if the current limit is active. Buck short circuit (VVOUT < 0.35V at 1 ms after enable) or Overload (VVOUT decreasing below 0.35 V during operation, 1 ms debounce) Converter disable BUCKx_INT = 1 BUCKx_SC_INT = 1 N/A N/A Write 1 to the BUCKx_SC_INT bit. Boost short circuit Converter disable BOOST_INT = 1 BOOST_SC_INT = 1 N/A N/A Write 1 to the BOOST_SC_INT bit. Thermal warning No effect TDIE_WARN_INT) = 1 TDIE_WARN_MASK TDIE_WARN_STAT Write 1 to the TDIE_WARN_INT bit. Interrupt is not cleared if the temperature is above the thermal warning level. Thermal shutdown All converters disabled immediately and GPOx set to low TDIE_SD_INT = 1 N/A TDIE_SD_STAT Write 1 to TDIE_SD_INT bit Interrupt is not cleared if temperature is above thermal shutdown level VANA overvoltage (VANAOVP) All converters disabled immediately and GPOx set to low OVP_INT N/A OVP_STAT Write 1 to the OVP_INT bit. Interrupt is not cleared if the VANA voltage is above the VANAOVP level. Buck power-good, output voltage becomes valid. No effect BUCK_INT = 1 BUCKx_PG_INT = 1 BUCKx_PGR_MASK BUCKx_PG_STAT Write 1 to the BUCKx_PG_INT bit. Buck power-good, output voltage becomes invalid No effect BUCK_INT = 1 BUCKx_PG_INT = 1 BUCKx_PGF_MASK BUCKx_PG_STAT Write 1 to the BUCKx_PG_INT bit. Boost power-good, output voltage becomes valid. No effect BOOST_INT = 1 BOOST_PG_INT = 1 BOOST_PGR_MASK BOOST_PG_STAT Write 1 to the BOOST_PG_INT bit. Boost power-good, output voltage becomes invalid. No effect BOOST_INT = 1 BOOST_PG_INT = 1 BOOST_PGF_MASK BOOST_PG_STAT Write 1 to the BOOST_PG_INT bit. VMON1 power-good, input voltage becomes valid. No effect DIAG_INT = 1 VMON1_PG_INT = 1 VMON1_PGR_MASK VMON1_PG_STAT Write 1 to the VMON1_PG_INT bit. VMON1 power-good, input voltage becomes invalid. No effect DIAG_INT = 1 VMON1_PG_INT = 1 VMON1_PGF_MASK VMON1_PG_STAT Write 1 to the VMON1_PG_INT bit. VMON2 power-good, input voltage becomes valid. No effect DIAG_INT = 1 VMON2_PG_INT = 1 VMON2_PGR_MASK VMON2_PG_STAT Write 1 to the VMON2_PG_INT bit. VMON2 power-good, input voltage becomes invalid. No effect DIAG_INT = 1 VMON2_PG_INT = 1 VMON2_PGF_MASK VMON2_PG_STAT Write 1 to the VMON2_PG_INT bit. VANA power-good, input voltage becomes valid. No effect DIAG_INT = 1 VANA_PG_INT = 1 VANA_PGR_MASK VANA_PG_STAT Write 1 to the VANA_PG_INT bit. VANA power-good, input voltage becomes invalid. No effect DIAG_INT = 1 VANA_PG_INT = 1 VANA_PGF_MASK VANA_PG_STAT Write 1 to the VANA_PG_INT bit. External clock appears or disappears. No effect to converters SYNC_CLK_INT(1) SYNC_CLK_MASK SYNC_CLK_STAT Write 1 to the SYNC_CLK_INT bit. Load current measurement ready No effect I_MEAS_INT = 1 I_MEAS_MASK N/A Write 1 to the I_MEAS_INT bit. Supply voltage VANAUVLO triggered (VANA falling) Immediate shutdown, registers reset to default values N/A N/A N/A N/A Supply voltage VANAUVLO triggered (VANA rising) Start-up, registers reset to default values and OTP bits loaded RESET_REG_INT = 1 RESET_REG_MASK N/A Write 1 to the RESET_REG_INT bit.
