PGOOD AND GPIO WINDOWS
The
PGOOD
and
GPIO
windows go hand in hand. Several
flags, such as IOUT_OC_FAULT and VOUT_OV, can be set
into PGOOD1 and PGOOD2 which are internal signals. These
can be routed to hardware pins GPIO1 to GPIO4 in the
GPIO
window.

Figure 61. Additional Settings in IOUT Window
The
GPIO
window configures the GPIO1 to GPIO4 pins either
as an input or as an output. If selected as an output, the pin can
output a logic combination of PGOOD1 and PGOOD2. If
selected as an input, then it acts as a digital input whereupon a
GPIOx fault can be triggered.

There are several logic operations available for programming
the output as shown in Figure 63.

COMMAND MASKING
The
ADP1055
supports command masking that can mask any
command (PMBUS command and extended manufacturer
specific command). When a read or write is made to a
command that is masked, the
ADP1055
returns with a NACK.
Commands can be masked in the command masking window
by simply clicking on the lock next to the command.

The commands that are locked/masked are then blocked out
from the GUI and the corresponding settings window is not
accessible.
