Description
SWRST OR VBSTx-VSWNx_UVth Monitor
0_B , no SWRST or undervoltage on the Gate Drivers occured
1_B , there was at least one SWRST since last readout OR an
undervoltage condition at the gate drivers is occurring
V_DD OR V_EN/INUVLO Undervoltage Monitor
0_B , there was no V_DD OR V_EN/INUVLO undervoltage since last readout
1_B , there was at least one V_DD undervoltage OR V_EN/INUVLO
undervoltage condition since last readout
Operative State Monitor
00_B , (reserved)
01_B , Limp Home Mode
10_B , Active Mode
11_B , Idle Mode
Transmission Error
0_B , Previous transmission was successful
(modulo 16 + n*8 clocks received, where n = 0, 1, 2...)
1_B , Previous transmission failed or first transmission after reset
End of LED/Input Current Monitor Routine Bit
0_B , Current monitoring routine not completed, not successfully
performed or never run.
1_B , Current Monitor routine successfully performed (is reset to 0_B
when SOMON is set to 1_B)
End of MFS Routine Bit
0_B , MFS routine not completed, not successfully performed or
never run.
1_B , MFS routine successfully performed (is reset to 0_B when
SOMOFS is set to 1_B)
End of Calibration Routine
0_B , Calibration routine not completed, not successfully performed
or never run.
1_B , Calibration routine successfully performed (is reset to 0_B when
SOCAL is set to 1_B)
V_INOVLO Voltage Monitor
0_B , V_INOVLO below V_INOVLOth threshold since last readout
1_B , There was at least one V_INOVLO overvoltage condition since last
readout
Output overvoltage Monitor
0_B , Output overvoltage not detected since last readout
1_B , Output overvoltage was detected since last readout
IVCC or IVCC_EXT Undervoltage Lockout Monitor
0_B , IVCC and IVCC_EXT above V_{IVCC_RTH,d} or V_{IVCC_EXT_RTH,d}
threshold since last readout
1_B , Undervoltage on IVCC or IVCC_EXT occurred since last
readout
