Bit
Function
Operation
D[7]
Reserved
Always write as zero; reads undefined.
D[6]
ADSTP
Stop ADC Halts the analog to digital
converter
0 = normal operation; 1 = stopped; Read/write.
D[5]
ADIDL
ADC idle flag
0 = busy; 1 = idle; Read/write.
D[4]
1SHOT
Triggers one-shot A/D conversion
cycle
0 = normal operation; 1 = one-shot; Read/write.
D[3]
ADSPIN
Selects ADC spin-on-channel mode;
do not enable ADC and FC spin-on-
channel modes simultaneously
0 = normal operation; 1 = spin-on-channel; Read/write.
D[2],
D[1], D[0]
SPIN[2:0]
ADC and fault comparator (FC)
channel select for spin-on-channel
mode; do not enable ADC and FC
spin-on-channel modes
simultaneously
ADC: 000 = temperature; 001 = voltage; 010 = VILD;
011 = VMPD; 100 = VRX; FC: 001 = VILD;
001 = VMPD; 010 = VRX; Read/write.

Default Value
0000 0000b = 00h
Serial Address
A6h = 1010011b
Byte Address
18 = 12h
The look-up table index is derived from the current temperature measurement and LUTOFF as follows:
where T
AVG
(n) is the current average temperature. This register allows the current table index to be read by the host. The table
base address must be added to LUTINDX to form a complete table index in physical memory. A valid OEM password is
required for access to this register. Otherwise, reads are undefined.
OEM Configuration 3 (OEMCFG3)
D[7]
LUTSEL
read/write
D[6]
TXFPOL
read/write
D[5]
GPOD
read/write
D[4]
GPOM
read/write
D[3]
GPOC
read/write
D[2]
TXFIN
read/write
D[1]
LOSDIS
read/write
D[0]
INTCAL
read/write
Default Value
0000 1000b = 08h
Serial Address
A6h = 1010011b
Byte Address
19 = 13h
This register is non-volatile and will be maintained through power and reset cycles. A valid OEM password is required for access
to this register. GPOD and GPOC are ignored when GPOM = 0. TXFPOL is ignored if TXFIN = 0.
