56 / 68 page  AD5560 Data Sheet Rev. D | Page 56 of 68 Table 25. Alarm Status and Clear Alarm Status Register Address Register Default Data Bits, MSB first 0x43 Alarm status 0x0000 This register is a read-only register providing information on the status of the alarm functions and the comparator outputs. Bit Name Function 15 LTMPALM Latched temperature alarm bit; if low, this bit indicates that an alarm event has occurred. 14 TMPALM Unlatched alarm bit; if low, these bit indicates that an alarm event is still present. 13 LOSALM Latched open-sense alarm bit; if low, indicates that an alarm event has occurred. 12 OSALM Unlatched open-sense alarm bit; if low, indicates that an alarm event is still present. 11 LDUTALM Latched DUTGND Kelvin sense alarm; if low, indicates that an alarm event has occurred. 10 DUTALM Unlatched DUTGND Kelvin sense alarm; if low, indicates that an alarm event is still present. 9 LCLALM Latched clamp alarm; if low, indicates that an alarm event has occurred. 8 CLALM Unlatched clamp alarm; if low, indicates that an alarm event is still present. 7 LGRDALM Latched guard alarm; if low, indicates that an alarm event has occurred. 6 GRDALM Unlatched guard alarm; if low, indicates that an alarm event is still present. 5 CPOL Comparator output low condition as per the comparator output pin. 4 CPOH Comparator output high condition as per the comparator output pin. 3:0 Unused Must be zeros. 0x44 Alarm status and clear alarm 0x0000 This register is a read-only register providing information on the status of the alarm functions and the comparator outputs. Reading this register also automatically clears any latched alarm pins or bits. Bit Name Function 15 LTMPALM Latched temperature alarm bit; if low, this bit indicates that an alarm event has occurred. 14 TMPALM Unlatched alarm bit; if low, these bit indicates that an alarm event is still present. 13 LOSALM Latched open-sense alarm bit; if low, indicates that an alarm event has occurred. 12 OSALM Unlatched open-sense alarm bit; if low, indicates that an alarm event is still present. 11 LDUTALM Latched DUTGND Kelvin sense alarm; if low, indicates that an alarm event has occurred. 10 DUTALM Unlatched DUTGND Kelvin sense alarm; if low, indicates that an alarm event is still present. 9 LCLALM Latched clamp alarm; if low, indicates that an alarm event has occurred. 8 CLALM Unlatched clamp alarm; if low, indicates that an alarm event is still present. 7 LGRDALM Latched guard alarm; if low, indicates that an alarm event has occurred. 6 GRDALM Unlatched guard alarm; if low, indicates that an alarm event is still present. 5 CPOL Comparator output low condition as per the comparator output pin. 4 CPOH Comparator output high condition as per the comparator output pin. 3:0 Unused Must be zeros. 0x45 CPL DAC x1 0x0000 D15 to D0. 0x46 CPL DAC m 0xFFFF D15 to D0. 0x47 CPL DAC c 0x8000 D15 to D0. 0x48 CPH DAC x1 0xFFFF D15 to D0. 0x49 CPH DAC m 0xFFFF D15 to D0. 0x4A CPH DAC c 0x8000 D15 to D0. 0x4B to 0x7F Reserved Reserved. |
