D[7]
Bit
Function
Reserved
Operation
Always write as zero; reads undefined.
D[6]
FLTDIS
Fault Comparator disable
0 = Fault Comparator faults enabled
1 = Fault Comparator faults disabled
When FLTDIS is high, the Fault Comparator does not run,
and the following faults are not detected:
?
?
?
High IBIAS faults
High transmit power faults
Low receive power faults
If a fault condition was detected prior to the assertion of
FLTDIS, the fault flag will remain active until cleared, but
cannot be set again until the Fault Comparator is allowed
to run.
D[5]
FSPIN
Fault Comparator “spin-on-channel” mode
select; do not enable ADC and FC spin-
on-channel modes simultaneously.
0 = Normal Fault Comparator operation
1 = Force the Fault Comparator to spin on one channel
When the Fault Comparator spins on just one channel
(selected via OEMCAL1[1:0]), the two channels not being
examined will not, of course, respond to fault conditions.
D[4]
WRINH
Inhibit NVRAM write cycles.
0 = Normal NVRAM operation
1 = Inhibit NVRAM writes
When WRINH is high, writes to the MIC3003’s internal
memory do not occur. Registers that are non-volatile are
written with the new value, but will not retain that value
through a power cycle, since the NVRAM backing storage
has not been modified.
D[3]
APCCAL
Selects APC DAC calibration mode -
DACs may be controlled directly.
0 = Normal mode
1 = DAC calibration mode.
When DAC calibration mode is enabled, the temperature
compensation lookup tables are disabled, so the DACs
are presented with the values written into their
corresponding registers.
D[2:1]
Reserved
Always write as zeros; reads undefined.
D[0]
FRCOPS
Forces outputs for board-level or system-
level testing
0 = Normal operation
1 = Force outputs for testing: The following outputs are
driven to their active states:
?
?
?
TXFAULT (active polarity set in OEMCFG5)
/INT (only driven if the OEMIM bit is clear in
FLTMSK)
RXLOS (active polarity and RXLOS selection are
set in OEMCFG6)
