DESCRIPTION
ADC Conversion Results
(Registers r00h to r17h)
Failed Line Flags
(Registers r18h to r19h)
GPIO Data
(Registers r1Ah to r1Bh)
DAC Enables
(Registers r1Ch to r1Dh)
DAC Registers
(Registers r00h to r0Bh)
ADC Range Selections
(Registers r0Fh to r11h)
DAC Range
(Registers r12h to r14h)
RESET
and Fault Outputs
(Registers r15h to r1Bh)
Input ADC conversion results. ADC writes directly to these registers during normal
operation. ADC input ranges (MON1–MON12) are selected with registers r0Fh to r11h.
Voltage fault flag bits. Flags for each input signal when undervoltage or overvoltage
threshold is exceeded.
GPIO state data. Used to read back and control the state of each GPIO.
Extended
DAC output control. Controls whether DAC outputs are high impedance or connected
to the DAC.
Default
DAC code registers. Sets the output voltage of each DAC output.
ADC input voltage range. Selects the voltage range of the monitored inputs.
DAC range registers. Sets the voltage output range of each DAC output.
RESET
and
FAULT1
–
FAULT2
output configuration. Programs the functionality of the
RESET
,
FAULT1
, and
FAULT2
outputs, as well as which inputs they depend on.
General-purpose input/output configuration registers. GPIOs are configurable as a
manual-reset input, a margin disable input, margin-up/margin-down control inputs, a
watchdog timer input and output, logic inputs/outputs, fault-dependent outputs, or as
the feedback/pulldown inputs (INS_) for closed-loop tracking.
Programmable output configurations. Selectable output configurations include: active-
low or active-high, open-drain or push-pull outputs. EN_OUT1–EN_OUT6 are
configurable as charge-pump outputs and EN_OUT1–EN_OUT4 can be configured for
closed-loop tracking.
Input overvoltage and undervoltage thresholds. ADC conversion results are compared
to overvoltage and undervoltage threshold values stored here. MON_ voltages
exceeding threshold values trigger a fault event.
Selects how the device should operate during faults. Options include latch-off or
autoretry after fault. The autoretry delay is selectable (r4Fh). Use registers r48h
through r4Ch to select fault conditions that trigger a critical fault event.
Use register r4Dh to set the
Software Enable
bit, to select early warning thresholds
and undervoltage/overvoltage, to enable/disable margining, and to enable/disable the
watchdog for independent/dependent mode.

Watchdog Functionality
(Register r55h)
Assign inputs and outputs for sequencing. Select sequence delays (20μs to 1.6s) with
registers r50h through r54h. Use register r54h to enable/disable the reverse sequence
bit for power-down operation.
Configure watchdog functionality for GPIO5 and GPIO6.
Default and

DAC Output Margin Levels
(Registers r66h to r7Dh)
DAC output levels depend on GPIO2 and GPIO3 when configured for margining
functionality. Set registers r66h to r71h for margin up. Set registers r72h to r7Dh for
margin down.
ADC conversion results and failed-line flags at the time of a fault. These values are
recorded by the fault event logger at the time of a critical fault.

Note:
This data sheet uses a specific convention for referring to bits within a particular address location. As an example, r0Fh[3:0]
refers to bits 3 to bit 0 in register with address 15 hexadecimal.
