Action on exception consists in “TRISTATING” driver. The driver operation can only be recovered by explicitly write DRVENA = 1. GPOExc[5:0] and SPIExc[5:0] signals are generated by ORing exception bits. NOTE: As monitors are working also during startup phases, when voltage levels can not be stable, it can happen that some fault bit are set to “1” after POR. To avoid false diagnosis when the device is fully functional, it is suggested to read this register once after the startup in order to clean it. [19:16] unused [15] T_WARN: Thermal Warning - Active high - Channel thermal sensor has exceeded “thermal warning threshold”. 0: no fault 1: Thermal warning Reset events: POR, DATA READ Actions on set: No actions related to this bit. Behavior: Read operation would reset bit status if channel temperature is below “thermal warning threshold”. [14] CRC error on CSA Compensation data: 0: No CRC Error. 1: CRC Error Reset events: POR [13] CRC error on A2D trimming bits: 0: No CRC Error 1: CRC Error Reset events: POR L9300 SPI interface and register mapping DS12258 - Rev 5 page 136/178 |
