Description
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.
Default. Disables generation of SMBAlert when the
PIN_OP_WARN bit is set.
Generates SMBAlert when the PIN_OP_WARN bit is set.
GPO2 is configured to generate SMBAlerts.
GPO2 can be used a general-purpose digital output pin. The
GPO2_INVERT bit is used to change the output state.
Default. GPO2 is configured as a retry fail output.
This is digital comparator mode. The output pin now reflects the
live status of the warning or fault bit selected for the output. In
effect, this is a nonlatched SMBAlert.
Default. In GPO mode, the GPO2 pin is active low.
In GPO mode, the GPO2 pin is active high.
Description
Always reads as 0000.
Threshold for the IOUT measurement through the sense resistor,
expressed in ADC codes. This value can be either an undercurrent
or overcurrent, depending on the state of the
IOUT_WARN2_OC_SELECT bit set using the DEVICE_CONFIG
command.
Description
Always reads as 00.
Enable operation command.
The OPERATION command is disabled, and the
NACK if the command is received. This setting provides some
protection against a card accidentally turning itself off
The OPERATION command is enabled, and the
responds to it.
