Write '0': No effect Read '1': The stored result for the corresponding auxiliary channel is less than UV_THRES_AUX*. AUX_UV_FAULT[0] corresponds to AUX0. If UNLATCHED_FAULT is set, this register is self-clearing. [7:0] AUX_OV_FAULT For each bit in this bitmask: Write '1': Reset the fault condition. Write '0': No effect Read '1': The stored result for the corresponding auxiliary channel is greater than OV_THRES_AUX*. AUX_OV_FAULT[0] corresponds to AUX0. If UNLATCHED_FAULT is set, this register is self-clearing. 7.6.3.31 FAULT_2UV 0x5A–5B (90–91) Comparator Undervoltage Fault BIT NAME DESCRIPTION [15:0] CMPUV_FAULT For each bit in this bitmask: Write '1': Reset the fault condition. Write '0': No effect Read '1': Corresponding battery cell comparator has detected an undervoltage condition. CMPUV_FAULT[0] corresponds to cell 1. When UNLATCHED_FAULT is set, these comparator faults only automatically clear if no other Analog die based fault exists. This is true even for faults that are masked. Analog die faults include FAULT_SYS[0:3] or any bit in registers FAULT_2UV or FAULT_2OV. 7.6.3.32 FAULT_2OV 0x5C–5D (92–93) Comparator Overvoltage Fault BIT NAME DESCRIPTION [15:0] CMPOV_FAULT For each bit in this bitmask: Write '1': Reset the fault condition. Write '0': No effect Read '1': Corresponding battery cell comparator has detected an overvoltage condition. CMPOV_FAULT[0] corresponds to cell 1. When UNLATCHED_FAULT is set, these comparator faults only automatically clear if no other Analog die based fault exists. This is true even for faults that are masked. Analog die faults include FAULT_SYS[0:3] or any bit in registers FAULT_2UV or FAULT_2OV. 7.6.3.33 FAULT_COM 0x5E–5F (94–95) Communications Fault BIT NAME DESCRIPTION [15] COMP_ERR_H Write '1': Reset the fault condition. Write '0': No effect Read '1': A bit on the high-side interface failed to compare with its complement. This is notification only; the frame is processed by the communications interface logic. [14] COMP_ERR_L Write '1': Reset the fault condition. Write '0': No effect Read '1': A bit on the low-side interface failed to compare with its complement. This is notification only; the frame is processed by the communications interface logic. [13] COMP_FLT_H Write '1': Reset the fault condition. Write '0': No effect Read '1': A frame on the high-side interface (COMMH) was stopped due to two or more complement errors (COMP_ERR_H). [12] COMP_FLT_L Write '1': Reset the fault condition. Write '0': No effect Read '1': A frame on the low-side interface (COMML) was stopped due to two or more complement errors (COMP_ERR_L). |
