Description
Disables generation of SMBAlert when the FET_HEALTH_BAD bit
is set.
Default. Generates SMBAlert when the FET_HEALTH_BAD bit is
set. This bit is active from power-up so that a FET problem can be
detected and flagged immediately without the need for software
to set this bit.
Default. Disables generation of SMBAlert when the
IOUT_OC_FAULT bit is set.
Generates SMBAlert when the IOUT_OC_FAULT bit is set.
Default. Disables generation of SMBAlert when the
VIN_OV_FAULT bit is set.
Generates SMBAlert when the VIN_OV_FAULT bit is set.
Default. Disables generation of SMBAlert when the
VIN_UV_FAULT bit is set.
Generates SMBAlert when the VIN_UV_FAULT bit is set.
Default. Disables generation of SMBAlert when the CML_FAULT
bit is set.
Generates SMBAlert when the CML_ FAULT bit is set.
Default. Disables generation of SMBAlert when the
IOUT_OC_WARN bit is set.
Generates SMBAlert when the IOUT_OC_WARN bit is set.
Default. Disables generation of SMBAlert when the IOUT_WARN2
bit is set.
Generates SMBAlert when the IOUT_WARN2 bit is set.
Default. Disables generation of SMBAlert when the
VIN_OV_WARN bit is set.
Generates SMBAlert when the VIN_OV_WARN bit is set.
Default. Disables generation of SMBAlert when the
VIN_UV_WARN bit is set.
Generates SMBAlert when the VIN_UV_WARN bit is set.
Default. Disables generation of SMBAlert when the
VAUX_OV_WARN bit is set.
Generates SMBAlert when the VAUX_OV_WARN bit is set.
Default. Disables generation of SMBAlert when the
VAUX_UV_WARN bit is set.
Generates SMBAlert when the VAUX_UV_WARN bit is set.
Default. Disables generation of SMBAlert when the
HS_INLIM_FAULT bit is set.
Generates SMBAlert when the HS_INLIM_FAULT bit is set.
