D[6]
FLTDIS Fault comparator disable; inhibits output
of fault comparators when set.
D[5]
FSPIN Fault comparator “spin-on-channel” mode
select; do not enable ADC and FC spin-
on-channel modes simultaneously.
D[4]
WRINH Inhibit NVRAM write cycles.
D[3]
APCCAL Selects APC calibration mode - DACs
may be controlled directly.
D[2]
FRCINT Forces the assertion of /INT
D[1]
FRCTXF Forces the assertion of TXFAULT
D[0] FDCLOS Forces the assertion of RXLOS
Operation

0 = faults enabled; 1 = disabled; Read/write.
0 = normal operation; 1 = spin on channel; Read/write.
0 = normal operation; 1 = inhibit writes; Read/write.
0 = normal mode; 1 = calibration mode; Read/write.
0 = normal operation; 1 = asserted; Read/write.
0 = normal operation; 1 = asserted; Read/write.
0 = normal operation; 1 = asserted; Read/write.

Function

Stop ADC Halts the analog to digital
converter
ADC idle flag
Triggers one-shot A/D conversion cycle
Selects ADC spin-on-channel mode; do
not enable ADC and FC spin-on-channel
modes simultaneously
ADC and fault comparator (FC) channel
select for spin-on-channel mode; do not
enable ADC and FC spin-on-channel
modes simultaneously
Operation
Always write as zero; reads undefined.
0 = normal operation; 1 = stopped; Read/write.
0 = busy; 1 = idle; Read/write.
0 = normal operation; 1 = one-shot; Read/write.
0 = normal operation; 1 = spin-on-channel; Read/write.
ADC: 000 = temperature; 001 = voltage; 010 = VILD;
011 = VMPD; 100 = VRX; FC: 001 = VILD;
001 = VMPD; 010 = VRX; Read/write.
