MFR_CHAN_CONFIG_LTC3880
General purpose configuration command common to multiple LTC products.

Reserved
5

4
Disable RUN Low. When asserted the RUN pin is not pulled low if commanded OFF
3
Short Cycle. When asserted the output will immediate off if commanded ON while waiting for TOFF_DELAY or TOFF_FALL. TOFF_MIN of 120mS
is honored then the part will command ON.
2
SHARE_CLOCK control, if SHARE_CLOCK is held low, the output is disabled
1
No GPIO ALERT, ALERT is not pulled low if GPIO is pulled low externally. Assert this bit if either POWER_GOOD or VOUT_UVUF are propagated
on GPIO
0
Disables the VOUT decay value requirement for MFR_RETRY_TIME processing. When this bit is set to a 0, the output must decay to less than
12.5% of the programmed value for any action that turns off the rail including a fault, an OFF/ON command, or a toggle of RUN from high to low
to high.
This command has one data byte.
MFR_CONFIG_ALL_LTC3880
General purpose configuration command common to multiple LTC products
BIT MEANING
7
Enable Fault Logging
6
Ignore Resistor Configuration Pins
5
Reserved, set to 1
4
Reserved
3
Mask PLL Unlock Fault
2
A valid PEC required for PMBus writes to be accepted. If this bit is not
set, the part will accept commands with invalid PEC.
1
Enable the use of PMBus clock stretching
0
Enables a low to high transition on either RUN pin to issue a
CLEAR_FAULTS command
This command has one data byte.
